Let us know how you like it.
PS. We have a demos thread for most of your needs, and a Windows 7 compatibility thread too (you can also usually find a Win7 thread in each game's forum).
Welcome! Hope you enjoy your stay. :)

Oh, also, check out Outcast. Graphics are neat, story fantastic and people you meet even more so. It's just not much of an RPG thou.
