7.5/10 Perfect tactical FPS. The variation in each game is perfect, though it lacks the player motivation to have full games and a constant community (which isn't very nice by the way)

10/10 This game will make you weep, laugh, scream, yell, turgle, and probably many other feelings. Everything can be interacted somehow. Hundreds of hours of gameplay.

8.5/10 This game is 'just great'. A must play with your friends. After some hundred of hours you'll realize why 8.5, and not 10. Performance decays, and the founder will not update it to Source 2.
