The one problem with Vista is you have to be patient cause all too often the high end graphics cards are not compatible. Saving regularly is a must! I haven't managed to get NWN to run on my new laptop yet sadly, but it doesn't appear to be because of Vista. Older games often have issues simply because Vista is not so good at the backwards compatibility.

I think my favourite would have to be NWN, although Guild Wars is a close second, and Sacred 2 is VERY close behind those two. It's so hard choosing a favourite because I love elements of all of them.

I'm not so crash hot at the lips (but I try real hard!), but sure will add you next time I turn on the xBox :D
