I consider the current investment system to be a problem. Very often there are situations when players can outgrow their associates in investments, and on the one hand, you want the buildings in the city to be of a higher level, and on the other hand, there are a lot of requirements in the top guilds, and it is very difficult to find something in between. Plus a lot of pressure on newbies and small guilds who find it hard to keep players with a lot of contributions.
As for me, you need to make two modes of city settings.
- normal - exactly the same as now
- Individual - when the levels of buildings correspond only to your contributions (that is, instead of 24700 ticks, you need to make 1/20, that is, 1235).
This way guilds will mostly matter for rankings/events and players will be able to choose what they want without having to change guilds every time you outgrow your guild or something like that.
there will also be an advantage for beginners, because no one will drive them like making investments at work, because those who have more investments will simply turn on an individual mode for themselves, and beginners will be in general, thus the entry threshold and pressure for beginners when looking for guilds decrease.
The setting is individual. If one player turned on an individual mod for himself, the rest may have a common one as it is now.
