There are some changes and differences comparing this one to the earlier one. Got better. Bit more of the instruments for controlling your company. I'm not Gina say it totally worth buying it, but I am not disappointed with buying it ether. From all of the "Game Dev" games on the market I'd put this one the upper half of of the list.
Edit:
Since I found no other way to contact your support, I'll leave this here: BUG - I'v developed own console in this game, spent all the money, it's all good and popular, but all the games I develop for it - come out developed for "PC" with minimal users, which obviously made me broke really fast.
Anyway - since I'm here, after couple of hours played - game could be better. Some features added, but still lack of some obvious ones already made in other games like this one
