How the hell are you gonna play RType with touchy controls. That just sounds like a poor idea. iPhones are going to be thrown at walls this Xmas.
The standalone R-Type game for iPhone is actually surprisingly good. I haven't played the Turbo version, though.
No buttons = no thanks. Except for maybe Military Madness - that one probably plays okay.
Actually, I played the demo of that one yesterday. Yeesh... It's tough to select the correct grid with the touch controls.
playing real games on touch screen is like playing a fighting game with a steering wheel, just play horrible, however, even though most mfi joypads are expensive and not so nice ( double price of dual shock 3 ps3 or xbox 360 joypad, yet not as good), hori has announced one and they are the best, have been making joypads and joysticks since nes/famicom era and are the pangani or Bugatti's of controllers, however, reasonable priced
