Dreamed for something like this for almost 10 years ^^
I like deep and complex games , so when i got used to the interface and most of the controls in About 2 weeks of learning (a long learning curve indeed) the real gaming began , and I liked it very much ... This was exactly what I was waiting for ... So for some people , I would recommend to try it first , and don't be to lazy to learn for some time , it might become great fun ... really ^^
P.S.
There are some issues with the game functionality , but you can make it work fully one way or another cause there are something like long ways and shortcuts to every function sometimes only the long way works ... have fun ;)
