Trine is a beautiful fantasy action platformer with a fairytale-like atmosphere, following the journey of three heroes - a Wizard, a Knight and a Thief - in a quest to save the kingdom from evil. The gameplay is based on fully interactive physics - each character's different abilities and tactics can be used to invent new ways to battle an army of undead and overcome obstacles, and restore the balance of the world.
How to justify this 10/10 rating. First - just run any demo or trailer for this game. Then - add physics, level design, music, narration and amount of love put into this game and.. you have it.
(actually there is some 0.3 points less for some small physics bugs and gameplay annoyances, but still it easily rounds to 10) :]
