To the moon and Waking mars question

To the moon is a great game if you like a good story and not care so much about the gameplay.
Havent played the other one.

It depends on the cards but they are both very good games.

Waking Mars is alright, though it's a bit on the short side and don't expect much replay value.

I think 20 cards are fair, To The Moon is an awesome experience, more like an interactive story with easy puzzles (3-4h).

Walking Mars doesn't appeal much to me, but To The Moon has cards so you'll get some of your investment back :]

To The Moon is not a game, actually it's a moive/novel in disguise. The story is only strong point of it.
But after I complete the game, it's not worth it. The story have plot hole and the ending is not truely happy.
Not recommended.
