Otomedius has a Burst attack, which will stop the game for a few seconds and give you time to touch the screen to target enemies. The 360 version works with a cursor, and Konami even released a bundle version with a special touchpad equipped stick. This went for around $450, so I didn't bother - if it cost half of that, I would've been tempted.
Shame the 360 didn't (and still doesn't) have a light gun or other pointing device. Otomedius would not be too bad with Project Natal support.
