Inno Games is now using fraud (they call it balancing or mistakes etc.) to generate revenue from long time players, they would never touch the new players as they are the upcoming cash cows.
Just read their beta forums feedback threads (warning: certain peoples posts are just a waste to read) to see they ways they are doing this. "We made a mistake" so it must be rebalanced which also means there will not be any refunds.
The most recent "fraud", they pushed content to live servers after beta testing in which apparently the testers warned/questioned them on a specific building, along with support tickets and other forum posts. Many players like myself deleted our premium buildings (they pretty much get deleted each new era anyway) for the better building and now they are saying it was a mistake they missed and they are going to rebalance it which will leave all players with negative population and the nightmare of having to correct it without the premium buildings we had prior (space is an issue in city building).
This is the nail in the coffin for me, as all the changes/rebalancing over the last year has just been to further their agenda of making money. I mean who waits over more than a year to decide something is not balanced (this is specific to an artillery unit)?
I was not a free player and did support the developers because I enjoyed it, but now that they are just screwing us over left and right I can no longer support this/them.
You may not believe anything I write just go read for yourself (until they get wise and start deleting threads/posts again).
Run far away from anything by this developer in my opinion.
