*EXTREMELY* light-hearted, cute, and funny (I mean, c'mon...there's "pout points" that can change/influence and/or affect just about anything & everything); along w/ some pretty amusing breaking-down of the 4th wall...
...My World, My Way -
is lots of (IMHO) good fun 
Haven't checked lately, but (being among Atlus' many low-print-run / hard-to-find games)...it might not be very cheap or easy to find anymore 
Yeah, it's become pretty rare because according to something I read, they discontinued it faster than they usually do (but that could be bollocks, I don't remember where I read this). Anyway, I own it too, and it's really fun and light-hearted indeed! There's a lot of grinding to do, though, but the story is fun. It caught my attention at the store because the games were shown from the side, and I saw ATLUS besides the really girly-looking title and wondered when the hell did Atlus start making girly games? So I searched the net for more infos, and decided to give it a go
I also have to recommend Lost Magic, it's often overlooked but it's a really great game! You're a mage and can befriend some monsters to aid you, and you attack by drawing runes on the touchscreen. The more accurate the rune, the stronger the spell. You can also mix runes to create new spells. The story is great imho, and the game has to be pretty cheap by now I guess. I really don't know why it was so overlooked.
