gyokzoli: You are not interested in RPGs,yet you preordered Witcher 2 which is an RPG. And if I'm not mistaken you want to take your pick among the games which you can choose free from with the preorder, right?
Well, they are all RPGs: Beyond Divinity, Divine Divinity, Gothic 2 Gold Edition, Realms of Arkania 1+2 and Realms of Arkania 3
The definition of RPG is very broad, and the Witcher has a lot of action-adventure elements compared to, for example, Fallout. I predicted many people would recommend the Fallout series which, among other things, has only turn-based combat, so I said I wasn't interested in RPGs.
DukeNukemForever: 5,99$, no strategy, no RPG, Win7 64bit and the use of mods or fanpatchs => Duke Nukem 3D
It normally runs with DosBox, but you can use
eDuke32 port to run it natively under Windows. There are also many mods, especially the High-Res for better graphics. The game itself is a nice old-school first person shooter and the mood is like Die Hard meets Aliens in a funny way.
Edit: You can find a
list of modsin the subforum.
Hm, thank you for the non-biased opinion. ;) Duke Nukem 3D wouldn't be a bad choice since I plan on trying out DNF.
