You gotta love a forum where the members run their own competitions - if you can make NukeJockey smile, you might win stuff!
Forum regular NukeJockey's recently gotten quite an entertaining idea - small, community-driven comps, often with the aim of just making him laugh, and/or cry. Possibly even hurl.
His latest one is running now, so if you like the idea of a random prize combined with some community involvement, you know where to look.
Make me a video of you playing your favourite game, with commentary over the top.
I don't care if its pong, wow, hello kitty, whatever, make me a video, make me smile, make me laugh, make me cry, give me some kind of reaction, I don't care what.
The commentary can either be in the form of a lets play, or of a review.
The video does not have to be serious, it can be satire/parody.
Just grab Fraps and record some footage and record your voice over the top if you want.
