Sounds like my kind of gamer.

I love those games, too.
My favorites so far (and I'm playing Tak and the Power of JuJu right now)
Jaq and Daxter (not sure of the spelling on Jaq) -- this one was clean and very enjoyable. About the level of difficulty of Tak, a little harder in some places. Good storyline.
Ratchet and Clank was a lot of fun as well, though I only got about 3/4 of the way through it. Another clean one, though the main idea *is* involved with getting different weapons and shooting characters. It is cartoony and I have no trouble with the "violence" in it compared to Tak, just wanted to warn it was lots of cartoony guns. I don't recall shooting any *people* in R&C, just bad guy monsters, and it is clean as far as cartoony shooting is concerned. The gameplay is fantastic, too. About comparable to a futuristic / sci-fi version of Tak and the Power of JuJu
Most recently, I really enjoyed Sphinx and the Cursed Mummy. Again, not too frustratingly difficult (though I'm not even half-way through it yet) while still having some good challenges, some humor in some areas, good clean fun. But the audio in Sphinx is seriously lacking. The only bad thing I can say about it, really.
There are sequels out for Jaq and Daxter and for Ratchet and Clank, but I haven't played the sequels. Yet.
Another good one is something about Ty the Tazmanian Devil or something. I think the name was Ty, anyway -- he's a cute orangy-yellow dog-type creature and had some good adventure.
I've heard that Racoon game was really good, haven't been able to find it to rent yet though and I typically rent games first with how expensive they are.
If you're willing to go back to PS1 games (which do play on the PS2, just need a PS1 memory card to save on), any of the 3 Spyro the Dragon games are *fantastic*, especially the third one. They're the closest to Tak and the power of JuJu that I've played in game style and humor. DO NOT get the Spyro for the PS2, though -- a different company took over the game when the PS2 came out, and I've heard nothing but complaints about the 4th game. But the PS1 Spyro games were top notch.
Have fun gaming!
