I see the PSP hate has evolved from "It has no games" to "most of its games are PS2 ports."
This is just as much nonsense as the first statement. Unless you have trouble *not* buying games you don't like, just skip the ports.
As I see it, there are a few categories here:
1) Ports. Tony Hawk, X-Men II, Madden, etc.
2) Enhanced ports/updates. Ridge Racer, Burnout Legends.
3) New games in old franchises: Twisted Metal, Wipeout, GTA, SOCOM, Virtua Tennis, Hot Shots Golf.
This seems to be the most popular category of PSP games.
In the case of TM, significantly different than the last.
In the case of Wipeout, different and much, much better. Best ever Wipeout, in my opinion.
In both those cases it's been a long time since the last game in the series.
SOCOM, HSG, and GTA are all games that benefit from the mobile or wifi aspect in one way or another that makes them appealing.
4) Original games in established generes. Lumines, Metal Gear Acid, LOTR Tactics, Untold Legends
5) Original games in either overlooked genres, or with a significant new twist. Loco Roco, Exit, Pursuit Force, Gripshift (horribly underrated game-- I said it before, if it had a popular mascot, this game would be getting huge amounts of positive attention).
Anyway, the complaints (other than people who acknowledge that it's merely their own taste) seem to focus on categories 1 and 2, and associate category 3 with the first two. To those folks I ask-- do you buy sequels to games? The PSP versions are merely sequels, which is not a problem with the PSP any more than it is the whole market.
