Entropia is not quite similar to Cantr

... I played it for a month or so earlier this year. The graphics are really really cool and if you want to know what I dream of as Cantr in the future - in terms of graphics - you should indeed look at Entropia

... But, although I was addicted for a few days, and played all day, in Entropia, it gets boring very quickly, I think. Cantr you can play for years each day a little bit; Entropia you can play all day, but gets boring after a while.
What I don't like, which why I say it doesn't look like Cantr, is that everything is predefined in the game. Even the exact organisation of societies is predefined, as are shops, the economy, etc. Politics are virtually absent. Who wins or loses a war is determined by the computer, based on the societies, not like in Cantr where this is much more complicated and realistic.
But I wish I could develop a game with the game dynamics and societies of Cantr in a user interface as Entropia's

...
And in Entropia you can play for free, but it's no fun

... I deposited just 15$ and that was enough to play nicely for quite a long time - but you need to deposit a little bit to get started.
