So there is 6 more buildings:
1) Development center - building it stops at level 12. The further people buld only microsystem accelerator due to it's greater impact on building/production time.
2) Weapons factory - building it stops at level 13. You got all ships unlocked at that level and making it further doesn't give you much. I've seen single players with level over 13.
3) Research lab - highest level I saw was at another player was around 25. Higher probably cost becomes really big (while it increases x2 every lvl) while it doens't give you that much time and as I know the max time of research is 365 days so when you get to that lvl or research upgrading research lab gives you nothing.
4) Teleporter - There are no major contraindications against upgrading the building, except if you will use it enough to use up all the energy. So again highest teleporter I saw was around level 12. Mostly players got around 6-8. They probably won't need more since they jump through all planets probably once/twice a day to gather resources.
And we have two more buildings that are probably only buildings that somebody would build with no limit:
5) Fleet base - every level is a benefit. Only thing to consider is if cost (that increases fast) is worth less then resources you will get from that additional fleet. And if you will send so many fleets at all.
6) Microsystem accelerator - shortening the construction time (mainly of the fleet) is always a good idea.
So thing I try to show there is that almost all buildings are not really worth building at some point. You can mainly build all of them at this 'max' levels until 600m points ( so you have x100 speed-up), so time isn't really problem here (at SI2). But what when you build them? Nothing, buildings doesn't really matter for you anymore. You can just stop thinking about them, there is no use in upgrading them. Another branch of the game (after defense) ceases to exist for you.
What can we do with this? I can't think about another idea then changing some basic rules and variables for the game itself. Like return rate of mines etc. Or changing that huge steps (in cost and time) between successive buildings levels, Here some big thoughtful change would be needed that would make the building system profitable for a long time (perhaps forever). Imagine if buildings would be like a fleet and you would upgrade them infinitly :DDD
Reserch - here the biggest problem is time. Cost of reserch is low. Only time for doing it is incredibly huge. There is not much to say. The single reserch is made for days, weeks and soon I will hit even months of reserch time. I'm not sure who thought about that but there is no much fun in clicking one button and then waiting for months for upgrade... The only thing which is saves research are events where you can shorten research time a little. I mean maybe it was fun 15 years ago when game was created to make something for 1000 hours but for now it's just boring.
If you are scared that too high research levels would disrupt the gameplay maybe for example decrese the bonuses research gives, drastically reduce the time needed for research, increse cost for reserch. It would be so much better if reserch would cost a lot and would be made faster then reversed.
Cause for now this is the third group (after defence and buildings) that is useless for big players. Also cause of that timings at certain point everybody got almost same reserch levels (cause big player must wait year for research while small player can make couple levels at this time until he also hits 1 year reseach time). The only difference between players becomes from how long they already play the game.
Fleet - probably the best thing game has to offer. The infinite system where you can get bigger and bigger, you can eat smaller players and grow faster cause of that. That is amazing idea that I think should be expanded at other aspects of the game. Can't really say much about it.
Maybe 1 thing that is really painfull is losing fleet that you built for years in single moment. Probably a lot of players decided to quit game after such expirience. That's why a lot of games introduced something like 'hospitals' (in medieval games) where you can at lower time/cost restore all/part of your dead units. That 'hospital' got it's capacity depending on it's level etc. So you still lose all your fleet but you are able to faster get it back, at least to some point.
But there is something about fleet flights. This flights are also slow and boring. And I understand that attack flights against other players must be little slow so player have a chance to react. But what about other flights: farming spacia, gathering rubbles and maybe some others? There is no benefit in this at all. Everybody would profit from faster flights the same way or maybe even active players would benefit more.
Activity - and here we go to the last point. If we want players to play game, the game must force the players to be active. And they must have something to do while beeing active.
If not then imagine login to game, start reserch that will be finished in months, the buildings are expanded to such a level that there is no reason to upgrade them more, so maybe send some flights. Yea I send flights, but they will be back in 3 hours. I will not watch game I have nothing to do in for 3 hours, so I go do something else, I forget about game. Next day I log in fleet is destroyed, I quit game cause it's boring anyway.
That's what is happening when there is nothing to do in game. Go play some popular games, they do everything to keep players all the time in game, and player love it. It's not fun to wait hours and hours for something in games. Now are times of immediate gratification.
So if your goal is to have active players you must give them reasons and options to be active. The days waiting for single thing without your contribution won't make players active. And also thing to think about is what really player get when they are active? Cause in normal game there is not really much advantage you get when you are active over unactive players. There is no option to really speed everything up by beeing active. And this is especially true when there are so few active players. With higher number of players maybe by beeing active you would be able to farm a lot of players and get advantage over rest of players.
Also for example chest events, there is also no real advantage for active players, that want to play the game cause there is limit of 100/150/200 chests for day. So probably every player that is playing can get all chests to this limit and that way everybody gets the same. Doesn't matter if you play 15 minutes a day or couple hours.
Ok I think I can finish here All in all, the game is boring. It's not only my point of view but also some other players I talked too. The further you go in game the less you got to do in game. But at the same time it has great potential with some minor and major changes and upgrades. If game will stay like it new players that have more interesting alternatives will not stay at game and old players sooner or later will leave the game too. Don't be scared of changes, game needs it, it's a lot of time since game started, it has to adapt to today's conditions
Also have to say that game have great admin/host/moderator Dschibait which for me personally turned out to be a great help in every matter and with him game just can't go down no matter what. So big shout out for him. Also I hope for best for this game. I hope you will approach my opinions with some distance and you will give your opinions too.
Do you think is game boring or not? Can't wait for your opinions
