I'm almost ashamed to say that I own a copy of Crash of the Titans. My only consolation is that I didn't pay a dime for it; it was my sister's, and she let me have it after she had to sell her hideously pink PSP.
I think I also got the memory stick she used, but I don't remember what happened to it...
If you can ignore how they butchered the characters (even if only a little), the game's not too bad. It's fun beating the shit out of things, and who wouldn't love to wreak havoc on a big-ass monster?
Personally, I always try to enjoy games for what they are; just games.
