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.
Atmosphere, humour and a well-polished gameplay are what makes Trine a game to try. At the highest difficulty the choice you make in leveling up your characters are really important and give the game an unexpected replay-value(along with all the secrets spread out in every level. Biggest disappointments are the lack of a multiplayer cooperative mode and the overall lenght(about 6-7 hours) along with some control responsiveness issues.
For this price you should definately give this game a chance.
