Here are some examples, all by the same guy:
Sonic doesn't need a story (http://alexdaymusic.com/sonic)
I hate Mario Kart Wii (http://alexdaymusic.com/mario)
Pokemon, what happened to you? (http://alexdaymusic.com/pok%C3%A9mon)
What A Horrible Night To Have A Curse - The Black Delilah Murder (http://www.youtube.com/watch?v=Y0d2LAgN-Q4)
It's about Castlevania; Can't remember which game.
and listening to the ones you linked right now.
