About ten years ago I asked my programmer pals if they'd help me make a game that's pretty much exactly what this game appears to be. They looked at me like I was crazy.
I'll be giving this game, Journey, a spin sometime in the future. It looks like the combination of meditative, relaxing and hypnotic which may be the sorts of effects lots of gamers feel with games they love, but I rarely find video games to have that effect on me. Running aimlessly through Grand Theft Auto did it, old school Nintendo and earlier Atari 2600 titles had that impact on me as well, and likely set the tone for my desires for more minimal games. Anyway, check out some of this video, 20 minutes of Journey game play. And, for more on the game and its developer, check out the site, thatgamecompany. (also, followup: some great thoughts on Journey by Jamin Warren on Kill Screen.)
