Great 2D shooter, the slowdown mechanic lets you feel like an action movie protagonist. The score system just makes it more satisfying to go back into a level just to do it perfectly.
Great 3D platformer similar to Mario 64 and Banjo-Kazooie, while also having it's own identity. All of the developer support and interaction with the community acts as the cherry on top of this fantastic game.
More of a roleplay than a survival horror most of the time, the roles you're given and the monsters you must evade can make the game tense, while the people playing it can bring in comedy.
