Oh wow, it's depressing how much better the Cartoon Network flash games are compared to their disc based counterparts...
The first one posted also looks a bit like a Billy and Mandy themed version of Donkey Kong Country, which is pretty neat.
But myself? Depends what you mean. For TV shows and stuff, I still remember the likes of Tom and Jerry, Scooby Doo, Dexter's Laboratory, Fairly Odd Parents, etc. Used to watch a lot of shows on Cartoon Network and Nickelodeon when I was younger...

Super Mario 63 too. That game was pretty awesome. Either way, I didn't used to know that you could get decent Mario fan games on PC, so the only ones I played were crappy flash ones on PC and Nintendo's official ones on consoles.
