I have a PSP with Lumines, Dynasty Warriors, Twisted Metal: Head-On, and Untold Legends. Out of those, Lumines is easily the most fun addicting.
I didn't like the changes made to DW for the PSP (battlefields divided into zones that you have to "liberate" by defeating all of the enemy troops in that zone), a lack of healing items (instead you have to heal at supply bases, which takes precious time away from the game clock), and sub-par graphics (at least when compared with games like Twisted Metal and Lumines). The only positive new feature is the ability to have the playable generals as bodyguards. It would be nice to see that in the console version. I also felt that the time limits on the battles were much too short. They barely give you enough time to finish, even if you take the most direct route to victory (which is annoying since I like to roam the battlefied killing every enemy general when I play the console DW).
Untold Legends was also a disappointment. I like Champions of Norrath and Baldur's Gate: Dark Alliance (from which the combat system in UL is derived), but I disliked this game. The load times are horrendous, and the lack of 4 shoulders buttons means that you have to press multiple buttons on the controller in order to
block. It would seem like that feature would be important enough to map to one button, but apparently Sony doesn't think so.
In contrast, Twisted Metal: Head-On is an excellent game, especially for fans of the series. There are some new cars, new maps, and redesigned versions of old maps (it was nice to see L.A. and Paris return, in particular). The graphics are some of the best on the PSP, and ability to play online is a nice bonus (unfortunately PSP ownership hasn't yet reached the point where I can find a lot of opponents
).
Getting back to Lumines, it is a great puzzle game. The gameplay is somewhat more similar to Tetris Attack than the original Tetris, since you are trying to form rectangles instead of lines. The different skins and music (which changes according to your peformance) add a lot to the game. Although I have not tried it yet, the wireless vs. mode seems very interesting.
When I went to see Star Wars Ep.3 on opening night, there were several people in the theater with PSPs. After seeing that, I will probably start bringing mine to movies so that I can take advantage of the wireless connectivity of the system
