Quite a few arcade style games available in the Gentoo ebuild repository.
Frozen-Bubble is a clone of the popular "Puzzle Bobble" game, in which you attempt to shoot bubbles into groups of the same color to cause them to pop. Players compete as penguins and must use the arrow keys to aim a colored bubble at groups of bubbles. The objective is to clear all the bubbles off the screen before a bubble passes below a line at the bottom.
It features 100 single-player levels, a two-player mode, game over LAN or Internet, music and striking graphics. A level editor is also included to allow players to create and play their own levels. View a YouTube demo here.

Open Sonic is an open-source game based on the "Sonic the Hedgehog" universe. It introduces a different style of gameplay called cooperative play, in which it's possible to control 3 characters simultaneously. Unlike most similar games, Open Sonic provides a greater level of interaction between the player and the levels. It's more than just a jump'n'run; the user must come up with some strategy in order to get through the levels. View a YouTube video here.
