Trine 2 was superior to its predecessor in every way, so much so that if you played the sequel first you might be disappointed with the original. To combat this, Frozenbyte has released an Enchanted Edition of Trine, which is basically a remake of the game in Trine 2's engine. Most importantly, it introduces cooperative multiplayer to the original, which means if you've played it before, you may very well want to play it again.

Trine was pretty fantastic when it came out in 2009 but Trine 2 was a major overhaul in just about every way, offering dramatically improved visuals and cooperative multiplayer that allowed the game's three lead characters – the Wizard, the Thief and the Knight – to be controlled simultaneously. Frozenbyte described those features as "missing" from the original game, and that's where the newly-announced Enchanted Edition comes into play.
