They offered a compelling experience, but not in the game sense. I think that's what the OP is trying to get across, and I personally think he's absolutely right. I am one of those gamers who usually will forgive a game for a lot of their downfalls if the story is great. Gameplay can be shitty for all I care, if I had a good experience. However, I will not deny that actually playing the game should be a big reason for winning an award like GAME of the year. Journey I felt was seriously overrated, because I didn't feel anything other than thinking it was a pretty game when it was all done. It was not fun in the gameplay sense, it was just a pretty easy diversion for 1-2 hours, and that was it. Journey was like watching an indie art movie where you happen to be holding a controller in your hand.
If you wanna talk about compelling, and different as an actual game that involves the player, I'd think Fez is more deserving of something like GOTY, because that was a game that truly was more then meets the eye.
