The Joy of Trine

The whole idea of finding the "joy" of a game is to side-step all the talk of whether it's fun and why.  Assume fun.  What else does a game provide once it's supplied you with the sine qua non of the medium?  That's the JOY.

Well, this one's easy.

The Joy of Trine is THIS.

Also: More, more, more, and more.
