SNOW is a skiing/snowboarding game which is going to eventually become a F2P MMO but currently is a singleplayer game that is very much in alpha. Right now all that's really in the game is the basic mechanics (there isn't even any sound!), but those are pretty solid most of the time (you won't notice any real problems just skiing down the mountain, but the tutorial course has some bizarre speed requirements for its jumps).

This is the "friend pack" which means you get beta tester privileges (so if any major changes are released in the future, even after release, you can play them in advance and tell the devs how you feel about them). I'm pretty sure you also get access to the alpha, but the store page is a bit unclear on this. You probably won't get any of the alpha-exclusive items, though.
