Lots of replayability, so it never gets boring, only more challenging! The art is beautiful too. And my kids (5 and 7) love it too! I also play alone as well, it's a great single player game.
Really enjoy the mechanics hopefully more trees come out as lil packs,
one good thing is it is cheaper than the same one from amazon
6 modules to play. The 3 solo modes are fun and challenging.
Not a must have, but a nice to have.
