Out of all the games I've downloaded (those being Gradius, Raiden, and Soldier Blade) Soldier Blade is by far the most addictive game on here. The touch controls seem to work best with it & the game itself is just awesome. A close second would be Gradius; the controls work well, but it's a tough game. The touch controls don't do Raiden justice, though, as your fighter moves so slowly you frequently have to do "flick" maneuvers, rather than D-padding the screen with your thumb, to get it to go where you want.
