Sure, there are a couple of nifty games on the PSP you won't find anywhere else. Metal Gear Solid: Portable Ops is one but still consists of many ideas already refined on other platforms. Lumines started on the PSP, but has since been released on Xbox Live Arcade and the PlayStation 2.
Don't get me wrong: I love good remakes. It's a weakness, and one I've not worked hard to eliminate. In my mind remakes like Ridge Racer and Hot Shots Golf: Open Tee were well worth my money. Even Ruffin, who normally chides me for indulging my appetite for these things, gifted me a copy of Resident Evil: Deadly Silence which consumed me for a couple of weeks.
But the PSP isn't doing much else nowadays. As far as the eye can see, it's remakes, rehashes, and retro collections.
In the next year we'll see the following on PSP:
- Castlevania: Dracula X Chronicles
- Parappa the Rapper
- Crazy Taxi: Fare Wars
- Final Fantasy I
- Final Fantasy II
- Taito Legends Power Up
- Elder Scrolls IV: Oblivion
Where is the PSP equivalent of Elite Beat Agents? Where is its Nintendogs or Brain Age? If Nintendo can pour money into original, unique projects and keep them exclusive to the Nintendo DS, why can't Sony do the same thing?
The touchscreen or the Wiimote might be considered gimmicks, but IMO they show a focus on gameplay. I like eye popping graphics as much as anyone, but that's not gameplay.
Back in January, I looked at upcoming games for the DS to see what games offered something innovative, even if marginally so. Spectrobes offered some variation on online play, allowing players to trade spectrobes and potentially create an online economy (which hasn't happened AFAIK). Lunar Knights makes use of the mic. Flipper Critters is munge of genres, of arcade and adventure. At least, I'm seeing some attempt in DS games that I don't see on the PSP. Traxion for the PSP was a step in that direction, but it's cancelled. Free Running could be interesting, but I have no idea if it's still in plan.
I know PSP fanboys argue that the PSP has lots of original titles and even more titles with a higher Metacritic rating than the DS, but though I desperately want a reason to own a PSP, I see not even one game that is driving me to it.
