I haven't played Koudelka yet(I haven't seen it anywhere...and I'm quitre broke at the moment). But I just bought Shadow Hearts about a week ago, and I'm about 10 hours in..it's really good so far. I really like it, and am looking foward to buying the second one ( when it goes down in price, of course...) It's really addicting. I like the battle system, with the fusion monsters. Story's intriguing so far. But we'll see.
