I'm not really a fan of anything Eidos aside from the Legacy of Kain series and various other single games.
I'd like to see another good LoK game. That series has always been a hit or miss I think. I loved the original Blood Omen, Blood Omen 2, and Defiance, but I disliked Soul Reaver and Soul Reaver 2. Defiance is more like a Soul Reaver title but much more enjoyable.
