So, as far as I can understand, Y Combinator chose to support other guys working on an idea that is exactly the same as yours? I can see two useful lessons to learn: 1. So, those guys already launched with your idea? And you really think that their execution is perfect? Think twice. Yes, "YouTube for games" would be nice in theory, but to tell you the truth I don't want to play it, and I'm sure there are quite a few people like me in this respect. Something is not there that would make me enjoy this. But I like watching videos on YouTube, go figure. You can think hard about the deficiencies that prevent Heyzap from being enjoyable (yes, I hereby state that it is not enjoyable) and do this idea, the right way. 2. What made Y Combinator choose them over you? Even given the obvious deficiencies you realised in pt. 1? In your place, I would ask PG nicely to tell why you didn't make it and the other guys did.
