I actually played the trial version recently and had a lot of fun (especially since the voice actress for the female wizard is Grey Griffin, who voices Azula in Avatar: The Last Airbender), now if only my wallet could catch up so I could just buy it already.... :p
I snagged Witchers 1&2 from a Steam sale a while ago, but I couldn't get into the first one, so I never gave the second one a try.
