I wonder if anyone else here even has a PSP aside from myself... my library consists of a handful of games that I wouldn't want to give up... except for maybe Mortal Kombat and Twisted Metal, which I got for free.
Though, a bunch of good games have been out for a while, so the price has probably gone down for them quite a bit, you could get them for 10-20 bux each on Amazon or whatever.
----- For example:
<b>Killzone: Liberation</b> - shooting in classic overhead perspective, take on waves of enemies while using cover, a dozen guns and a couple vehicles. Here is a <a href="

<b>Monster Hunter Freedom</b> (or MHF2, still 30bux) - If you want one man against gigantic monsters action that takes preparation, resource gathering and using all of your guy's skills and very large weapons to prevail against insurmountable odds (also many, many retries), then try it. You will spend a long time getting through everything in the game, and the experience is worth it... don't go giving up because something as weak as the Yian Kut-Ku is kicking your ass.
<b>Castlevania: Dracula X Chronicles</b> - A remake of a classic PC Engine Castlevania, a solid action platformer that comes packed with its fully-intact original 2D version AND the Playstation "Symphony of the Night". The new version (with two characters and lots of side-paths), the original version (when you unlock it in the new version (also two characters and sidepaths)) and SOTN (when you unlock it in the new version) could last you quite a long time.
I could snail mail you Mortal Kombat (awfully simplistic one-on-one fighting with horrible animation) and Twisted Metal (destruction derby deathmatch with rockets and machineguns), you might get some time out of them.
