Best RPG of all time is Baldur's Gate series.

I think it's all opinion. I haven't played Baldurs Gate, so I cant judge it, but I have played Diablo, which my friends say is the greatest RPG of all time, and others I can't recall. To me personally Skyrim is the best, the graphics the norse inspired story and mythology, it felt like I was living an old norse story. And this goes into other games like Oblivion, which I was completely bored with.

we need a good slavic inspired rpg ;)
