dsPIC33 has a great performance parameters. It provides a power enough to drive 320x240 display with GLCD or TV output.

The RBox is a game console that is simple enough to build on the prototype area of a LPCXpresso ARM dev kit. You need just a crystal, a few capacitors and resistors. It uses the smallest and cheapest 32 bit CPU to generate 3D graphics and sound.

This is really great board: AVR Ethernet I/O board with 2x RS232, 2x USB connector, BW composite video, Real Time Clock with battery backup, PS/2 keyboard connector, Wiz810MJ ethernet module and LCD 16x2 display.

Simple oldskool TV game based on Arduino.

Don't throw out your old ISA VGA cards. Sure, you can use them in the regular way in your PC, but you definitelly can use them in your hobby devices. For example with an ATMega128.
