We there are a few games that I'm playing a fair bit of on the PSP:
Lumines:
So far I've completed all the timed challenges, Finished Vs CPU mode and been playing on the Challenge mode for over 1 hour and 15 mins. I've got up to the 4X4 Puzzle on Puzzle Mode. Challenge mode high score: 423906. Timed Puzzles: 60 seconds: 56, 180 seconds: 168, 300 seconds: 271, 500 seconds: 510.
So I've got about 3 skins left to win. 1 for getting over 999,999,999 points, & two for completing Puzzle mode which is bloody hard.
LocoRoco:
I've gone through the game once and I'm currently going back through trying to collect everything and beat the times. Not as easy as I'd like it to be but frustratingly fun.
Metal Gear Ac!d:
I've completed it through once and I'm now playing a fair bit of link gaming as it's a good way to win points and buy cards. 168 of 204 crads collected.
Metal Gear Ac!d2:
I'm not playing this much at the moment but have completed the story mode twice on easy and once on both medium and hard. I used the trick of playing the Areana mode to gain points I recommed just playing it on easy loads until you've the cards you need or the cash to buy the ones you're after. 495 of 565 cards collected.
WipeOut: Pure:
As you can see from my previous entry I've been downloading the expansion packs. I've got gold medals on all the current tracks including the Omega pack tracks on Vector & Venom class. As well as Golds on the first two tracks on Flash class. I've also been having a go at the Time Trials but so far I've not got any golds yet.
I'm currently given the status of Geek as I've got 38 Golds in total.
