Are there any MMO/RPGs based on reality as opposed to magic/spells etc?

Sorry that question is phrased really badly.

I love the idea of MMOs and RPGs, but I really can't stand anything to do with magic/orks/spells/special powers and the like.

Are there any of these types of games based on reality. Something like a GTA style world (not exactly but hopefully you know what I mean) with real people and relatively realistic graphics?

I'm looking for something on Android (just rpg) or PC.
