It arrived, all the way from the USA:

Disgaea - Afternoon of Darkness
It is perfectly sealed. No holes, no scratches on the covering plastic. Mint. But do I play it? Took a while to find, I have a few games on the go right now (Fallout 3, FF VII, Monster Hunter and SOCOM) and if I do open it the resale value falls considerably. Metacritic scores it very highly which is one reason why I bought it. Not sure so for now it can safely with all the other games..
You could just install custom firmware on youre PSP and download a copy, play that and keep the original sealed
An excellent idea – I have found a copy I can use for a backup. Just bought a 3000 so I can mod the original 1000 I have.
Tim Minchin – I think I’d watched too much on Youtube because the dvd wasn’t as good as I thought. I’d seen all but one music track and some words I’d caught too. So it was good for the better quality but less so because I know what was coming next. Apart from the bit where is tells his daughter that she shouldn’t eat the coin, that her mouth is for food… which made me laugh.
The sequel, Disgaea 2:Dark Hero Days, is kicking around the web now as well
