The term is almost meaningless.
CRPG: any game with a protagonist gaining experience points or some similar form of character progression, that isn't called something else instead.
Diablo is labeled an RPG, action-RPG to be precise, and it has none of the fancy choices or in-depth characterization most regulars here like their games to have.
Strategy games often have units gaining experience and becomeing more powerful, but are not called RPGs. Something similar is happening with online shooters that hand out perks: still FPS, not "RPG" or "RPS".
Bioshock? Good question. Definitely hits all the criteria for a roleplaying shooter.
