10. ****
I'm leaving room for 10 here, because the order might change once I get my hands on Bayonetta which could turn out to be the next step in the action genre (and thus mind-blowingly awesome). If not, add either Resident Evil Remake, Silent Hill 4 or Yoshi's Island there. I don't know. IT's hard picking out a Top 10, usually it's easier for me to give a Top 3 because they're all 10/10 to me
The only reasons why Alundra beats Okami is because the "voice-acting" in Okami is annoying, and the story in Alundra was a tad better to me - more correctly, the story in Alundra had me more engaged. Project Zero ends up third because of the camera thing. I know, they couldn't have done it better, but it's still a drawback :P
