we need a good slavic inspired rpg ;)

We have one :)

A whole series, in fact. The Witcher trilogy, as already mentioned.

By the way, Diablo isn't all that much an RPG. Though there is character development, there is no choices, etc. It's very linear and pretty much a "go here, do that" sort of game.

Fun and all, but no one who has actually played a good RPG would ever consider it for top contender award. Wouldn't even place it in the top 10.
