I want a classic shooter upward scrolling, dont care about all this 3d lark... just like in the old days... I know they released one for the nintendo ds recently, but would love to see something for the PSP - anyone got any ideas?
There have been some shooters released in Japan. A couple of horizontal scrolling ones out now are Sengoku Cannon and Gradius Portable ( which includes 4 past Gradius games ). If you're particularly looking for vertical shooters then there is only one I believe and that is Star Soldier by Hudson, also Japanese. If you don't mind importing and are OK with playing Japanese games then that is probably what you're looking for.
