Runescape is probably the one free mmorpg that most CEtizen are familiar with. However I don't think it's the grindiest one. UltimaOnline is older and thus it's probably grindier than Runescape. Tibia is most likely grindier than Runescape. That game doesn't have a freaking level cap!!

For single player game, I remember playing a puzzle game where you could enter the exact seed number to generate the playing board. I can't remember the detail but assuming they used 4-bytes as seed, completing all possible board would take ages. 4.29 billion board is no joke.
