My favorite: Pipe Rush,
(made me play it the longest time from the entries)

Very nice collection of games. A lot of effort put into them.
This shows nicely what 3dGs is capable of.

Critics:

Some games did not include the d3dx9_30.dll !!!
Are the players supposed to know and install this dll?

Some games are visully better than pipe-rush, but either
they had bad controlls, or a too simplistic gameplay.
(The game should be very easy to play in the beginning, especially
in casual games, to make the player get into it, and like it.
Later it should get harder)
