Black Tiger already listed everything in the previous topic.
For multiplayers, I'm a big fan of Faceball, Bonanza Brothers and Galaxy Deka Gayvan.
I love the PCE racing/driving library: Outrun, Power Drift, SCI, and Motoroader II. Racing Tamashii is good, but try before you buy. Road Spirits sucks.
Battle Ace is under-appreciated on the SGX.
Psychic Storm is my favorite sleeper shooter.
Götzendiener, Magicoal, and Brandish are the closest I can come to RPG's without language skills. I tried Wizardry III-IV and while the menus and play mechanics are in English, not being able to read the dungeon warnings and interaction sucks.
