I bought PSP too early (December 2005). I paid 339€ from it with 1Gb memory stick and year later price was something like 200€ for PSP and 1Gb memory stick. It is great piece of hardware but at that time there was not too many good games in the market and that 339€ was more than I paid from my X360 and PS3....

World of Warcraft and Oblivion

Deadly Creatures and DBZ: Budokai Tenkaichi 3 (BT2 was soooo much better than this crap)

prince of persia and redfaction guerrilla

the first socom psp game,

ghost recon 2.... destroyed the series for me...... splintercell da...... hopefully the next one will be better but been meaning to give this game another try..... burnout revenge the load times oh my god the load times, fixed with paradise city "test drive" from last generation, completely threw away the good will earned with 5 and 6 prior to it

My Sims, Soul Calibur Legends, Alone in the Dark, PES 2009

Still life 2

Since got a ps3 40 gb on March 2008, motorstorm, ninja gaiden sigma and nba 2k8.

PC - oblivion and conflit: global storm.

you just bought all the wrong games, should of done Modern Warfare, Assassins Creed, GTA4, MGS4, Uncharted, GT: Prologue, etc....

I regret spending 10$ on Lair.
