Games where the plot revolves around a corrupt religion etc

While it's more of an action/strategy game with RPG elements, Kingdom Under Fire: The Crusaders' plot focuses quite a bit on that aspect. In fact, later on they were worried that the message about a corrupt church might be a bit TOO strong, they changed all references to the "Pope" (a major character in the game that's responsible for the religion's corruption, unsurprisingly) to "Patriarch", except they had already finished all the voice acting for the game and ended up blotting out the word Pope whenever it was spoken and only changed the subtitles to say Patriarch.

Soul Reaver 2, while again not a full RPG, also has a fair share of it's story dedicated to a fanatical religious group (which you spend most of the end-game fighting against, and it also has one of the more unexpected end bosses out there...even if it does kinda defy logic). Also, Deus Ex: Invisible War had a fairly interesting take on a religious group. It isn't really corruption as much as it is deception, but it's still a notable part of the storyline. Although once their true purpose is revealed to the player, their involvement drops off considerably.

And finally, Shining Force 3 (a strategy/RPG) had you fighting a crazy cult/religion for a bit of the game. Unfortunately, Scenarios 2 and 3 dealt with them more, but only the first scenario was made available outside of Japan.

Jam it back in, in the dark.

Err, isn't that kind of how it is? Because most religions still have a following even after they've been proven incorrect or just plain crazy. I mean, look at Scientology.

There's nowhere I can't reach.
