Risen 2? Risen was rather shite and I haven't really heard much good about no.2!?! Perhaps the PC version is better, or modded, but the 360 version is piss-poor.
Risen was excellent. Risen 2 on the other hand, has been roundly panned for a number of shortcomings. Some of them were addressed in a patch, others weren't.
EDIT: The ending for Risen was one of the worst of all-time though. Utterly dire and left me feeling as though I'd been robbed.
