The Best RPG is...

In Real Life is the best rpg in the world. Not only does it have first person view,sim mechanics,a varying economic system,rts,turned based strategy,modding support,gta like mechanics,racing,etc you could almost say its like living in the real world XD.

On a serious note,I do not believe there is a "best rpg" simply because that would mean its a rpg that is the best of every rpg genre and I have yet to see one of those :3.

JRPG: Chrono Trigger and Mother 3 are tied.
First person RPG: System Shock 1 and 2.
Western RPG: Fallout.

Arcanum Of Steamworks And Magick Obscura

Star Wars: Knights of the Old Republic or Mass Effect 2
