The A4000 and 1200 will play almost all the games. 1200 and 4000 use th AGA chipset, but some of the older games such as shadow of the beast will only play on an a500, 2000 or 2500 because they require the OCS (original chipset) and AGA will start the game but it will freeze shortly after start up. A few games I know will not work on and AGA(A4000 or 1200) or ECS (A3000) is Shadow of the beast and Defender of the crown. If you have an A500 and A4000 to say you will be pretty much covered. Also to note Amiga CD32 games will work on an Amiga computer, but requires the AGA chipset.
