Why don't you buy games for your PSP?

After buying PSP1000, PSP3000 and 55 original UMDs, all i can say is that PSP is a fantastic system with great games.
It's a completely different experience from a tabletop console.
At home, i usually game on my ps3, but there are moments (games) when i simply prefer psp. It's like PS3 is more intense, more visually impressive, 5.1 excellent sound and all but with my psp i find different qualities: more puzzle platform and arcade games which i love, this excellent standby function that allows you to play in very short bursts, a more relaxed way of playing, and of course all the benefits of being a handheld. I travel a lot and have a wife and daughter with their share of 50'' tv time lol.
Dissidia, Monster Hunter, Locoroco 2, Gran Turismo, GTA CTW, Pixel Junk Monsters Deluxe are some of the gems i've been enjoying lately.
I see a lot of people tend to evaluate the psp and it's games as if it was a ps3. I think they really don't like handheld gaming as it is today.

Oh, and of course, because you make an intelligent question (why don't you buy in opposition to why don't you play) i say i buy because i have respect for the creators, i like owning a case, i like being "legal" and because i have money to do it.
