Originally, this poll was about isometric rpg games. Then again, the first poster also mentioned Crusader: No Remorse and Crusader: No Regret, both aren't RPG games, just isometric action games.
Then the poll sort of grew into RPG games, or just plain fantasy games into about any genre really.
Thief isn't an RPG, but it's still more fantasy RPG like than for example Crusader: No Remorse, or Half Life.
