Just correcting some info:
- The world ends with you cant really be seriously played with stylus only. The "auto mode" AI for the partner wont survive the hardest boss battles, you gotta do it yourself.
- Ninja Gaiden is pretty much impossible, as you can't block or roll withour holding some button.
- Big Bang Mini also forces you to hold a button for the Homing Shot quite often. There are parts where it will be either too hard, or just impossible without it.
Adding some games:
- Planet Puzzle League (go online if you can)
- Final Fantasy 12 (scrolling the map with stylus can get a bit boring sometimes, but you can use same hand to press the d-pad and the shortcuts)
- Point Blank (Arcade-like shotting minigames)
- Fell The Magic & The Rub Rabbits
- Final Fantasy Tactics 2 (this is surprisingly nicely playable with stylus only, but a few shortcuts on d-pad comes handy sometimes)
- Club House Games
- Elements of Destruction (Reversed Sim City, you gotta destroy as much as you can)
- Looney Tunes Cartoon Conductor
- Meteos
- Nintendo Touch Golf
- Pac'n Roll
- Pac-Pix (Repetitive on first worlds, but gets interesting and challenging halfway through)
- Sonic Chronicles: The Dark Brotherhood
- Super Monkey Ball: Touch and Roll
- Taiko no Tatsujin 1 & 2 not the harder songs, as will be hard with only 1 stylus, but you can also use your 2 fingers nails from left hand to tap each drum).
- Wario Ware: Touched
- Peggle: Dual Shot
- Chronno Trigger (might take some minutes to get used to stylus play, but its ok)
- Riz Zoawd (Japanese, but really easy to play dungeon crawling rpg based on Oz Wizard with stunning graphics)
- Quick Spot (addicting and fuuuuun, on Rapid Play mode)
- Dragon Ball Origins (Like Zelda, you might miss some shortcuts, but pretty doable without them)
- Polarium
- Arkanoid
