Oblivion, for having horrible gameplay* and writing, dialogue minigame, being loved by LARPers all over the world and plaguing the game industry with the new buzzword ''immersion''.
Mass Effect, for having horrible gameplay, introducing popamole to RPG combat and dialogue wheel to RPG dialogue system, having an abysmal UI, being called RPG while not being RPG and plaguing the game industry with the buzzword ''cinematic''.
Alpha Protocol, for having horrible gameplay, following in the footsteps of Ass Effect for popamole and adding a touch of inanity to the already inane dialogue wheel and continuing the ''cinematic'' trend.
All three have in common that they offer next to nothing in terms of gameplay.
*combat, character system implementation, quests, levels, non-combat interaction, etc.
