Best 2 or 3 video-sharing sites (not YouTube) to upload gameplay videos to?

[GamePlayer565]

I've made around 40 Gary's Mod gameplay videos of different servers and another 300 videos of various games and indie games and so on.

I want to be able to upload the videos to a video-sharing website platform so I can monetize the videos thru advertising. I don't want to use YouTube because I am already using YouTube to monetize a non-gaming channel.

So does anyone got any idea what are the best places for video monetization?
