The thing is for a game to be good and entertaining for me it must have a fair share of elements that is often only found in CRPGs. I look for character development, story progression, challenge level, environment interactivity, combat, and so on.
I don't just play a game for what it is because if it doesn't have what I am looking for I just don't see it as entertaining. Diablo is a boring game. It will always be a boring game for me.
