Okay, I've just seen the game, and frankly is a mess. A friend of mine bought it today, despite my warnings. Now he awaits for Monday morning to return it. This game is quite a mess: poor controls and a lots of bugs are just a few turnoffs. Also the poor optimization it can drive crazy most of the people. Yes, the graphics are nice, but everything feels so half-baked, so rushed. No amount of patches could solve the mess that the fifth installment of AITD is...
And yes, you need the DVD in drive after activating the game
And I had so many hopes for this one. I'll stick to not buying it. Atari should really stop rushing things(TDU and the NWN2 are other fine examples of Atari rushing their titles out, but those two had problems that were solved in the patches, thing that i can't really see happening with AITD5)
