I would say that most id software is great, half-life, unreal, etc... the good FPS games.
Also... the whole final fantasy series (I am play FF2 on FF Origins for PSOne right now).
Neverwinter nights.
Warcraft 2 (not 3, it was a fluke)
Total Anihilation
Tetris! well just for old times sake.
Mega man series.
Mario 1+3.
Castlevania.
Worms Armagedon/World Party.
Alpha Centauri (Only when I have a long strech of game playing to get through my system)
As for PPC: Snails, Chess (pick you fav), GO, Nethack, Solitaire (Just when your mind is mush but you need something to do), Pocket Quake, Wolfenstien 3D, and sokoban (I used to have a version i developed but I have lost it since i sold my PPC).
What I would like to see (might exist already but I am to lazy to check now):
--Advanced Wars like game
--Better platform games (mario/megaman stuff)
--A good port of a D&D engine (are there any good ones yet?)
--Warcraft II (too bad freecraft was shut down by blizzard!! I can't stand them now. They used to rock but now they have no clue what makes a game any good.)
--I think it would be cool if developers started releasing "demos" or in other words a show off of the PDAs (high end, you pick your type) graphical, and audio capabilities... I have seen a few but more is always better
