If it wasn't for homebrew I probably wouldn't have a PSP. I bought it knowing it could run homebrew. There is simply nothing published I currently want for it. The only game I truly wanted was Tony Hawk. I bought GTA just to have it though I am and always was 1.50 but now I can emulate it through Devhook so it gets played but it sat for months still wrapped up before I learned about Devhook. Of the three UMD games I own GTA was the only one I bought new. I pour over the shelves at my local gamestop and see nothing that compells me to buy it. I'd have to say for a handheld system this has to be one of the worse in terms of available titles that appeal to me. It's taken a long time to get the amount of releases we have and I really don't care for much of it.
Then there are the movies the price point killed them as no one in their right mind is going to buy a umd movie for equal to or more then it's dvd counterpart. Especially when you can rip your dvd's and watch them on your psp.
I just feel disappointed with Sony's support of it's umd format and wonder how it will handle Blue Ray which it will try and shove down my throat with the PS3. I had visions of playing my UMD games on my PS3 then sync'ing my saves and taking the games with me on the go again. I envisoned content that would only be unlockable when the umd game was played on the PS3. Maybe special characters in a Final Fantasy game that you could only unlock by playing through the PS3. However none of this is going to happen but hey it's a Blue Ray player!~
