Tactics is a great game in my opinion. You should defenitly check it out.
Other ones I like that you haven't listed are:
Hot Shots Golf: Open Tee 2 - Cute, addictive golf game. If you've played Mario Golf it is a lot like that
Wipeout Pulse - Futuristic Racer, fast paced and lots of races, my favourite racer.
Sega Genesis Collection - Lots of great Sega games, Sonic 1 & 2, Vectorman 1 & 2, Phantasy Star II - V, Flicky, Golden Axe I - III, and so many more. Now with a save + load function.
Lumines - Addictive puzzler, fast paced tetris comes to mind.
Grand Theft Auto: Vice City Stories - Classic GTA on the go.
SOCOM: U.S. Navy SEALs Fireteam Bravo 2 - Still with a populated online, it's a fun shooter.
Dungeon Siege: Throne Of Agony - Underrated RPG, if you've played the PC games you'll love it, reminiscent of Diablo.
