After hearing a lot of really encouraging things about Resident Evil: Revelations, a single-player mode that only lasts for 10 hours is very disappointing - especially with the higher-than-normal pricing.
Then again, if the game is 10 hours of awesome thrills and chills then I'll be satisfied. Unlocking online multiplayer modes after the main game should keep the game fresh, and if this game is anything like RE4 then replay value shouldn't be a problem.
