Yeah I see where you are coming from. It's just that I looked at the pile of my games and gutted them out, picking the ones that I just do not play any more and woah when they add up, it comes to the price of the PSP so I thought what the heck.
I'm in no way expecting as much as I did for the DS because I love my DS and it's gonna be hard for the PSP to beat it. I figured it out by saying I want an MP3 player and a Portable DVD machine and PSP offers that and the games come as the extra to me. I have a DS to play games.
So I had money floating around so I decided to buy one. And for the UK'ers this is what my pre order looks like; sad i know but i'm bored.

My trade in list of games.

One of the biggest credit notes you'll be likely to see for a while.

And there it is, my token to gaming in even more heaven than I am now.
