If a game is good on console, why is it boring on PSP? Handhelds aren't, for 100% of the gaming population, about games that can't be played on consoles, and it's wrong to assume everyone wants non-console like games on PSP. Some do, and some don't. eg. PES on PSP is a very good way to play sociable football gaming anywhere. Handheld gaming is about being able to play games you like when and where you like, whether those games are simple pick-up-and-play games or sports sims of FPSs.
You're ignoring the very good processing power. nGage and DS aren't able to play Mercury because they couldn't process the phyisics fast enough.To play portable movies in a handheld, for one reason. A large highres screen is a great boon for games. Lemmings, or worms, or Soccer, benefit greatly from the larger playing area.
Except a GB isn't going to manage LocoRoco's graphics. As I've said, a DS probably wouldn't manage them either. They're quite high poly vector graphics, not all bitmaps. Also what if you want simple graphics with great gameplay AND complex games with good graphics and great gameplay like Syphon Filter AND portable console gaming for when you want to play those console favourites like PES when out and about? PSP gives you choices.
And I've already answered that several times, though this is totally off topic and I don't know why your comments on this game are just about the value of PSP as a gaming platform. You seem to have been concerned only with saying that this game shows how pointless PSP's 3D abilities are
If you want to play complex multiplayer games like Syphon Filter and PES without being tied to a TV, PSP is the only handheld platform worth considering. If you want processor-demanding games like Mercury, PSP is the only platform to go with. If you want fun 2D games like Worms or Lemmings that aren't claustraphobically small in the playing field department like GBA and DS, PSP is the only platform to satisfy. If you want portable 2D games that are substantially animated using striking vector based graphics instead of static bitmaps, the only platform with the graphics power to pull that off at the moment is PSP. If want a platform that plays fun, simple games, you can get a GBA, but if you want a platform that can do those games AND more complex and graphically impressive games like Syphon Filter, giving you more choice, PSP is the only option. You can buy a GBA and get fun games with simple graphics. You can get a DS with great games and some varied graphics. But neither of those is going to offer the range as PSP does. Neither of those is going to give you the console PES experience sat out under a tree on a sunny afternoon playing with your friends. Neither of those is going to let you roll a blob of mercury around a complex series of puzzles. And if the only reason to buy a PSP is for games, and you are attracted to the games on GBA and/or DS too, you'd probably be wasting your money on the system. PSP isn't and never was just a games machine. If you're only buying it for games, but don't want portable console games and don't care for improved graphics and aren't too fussed to have different styles of games ranging from 2D shooters and puzzlers to 3D racers and FPS, go grab one of the cheaper handhelds! You weren't Sony's intended audience anyway.
