you got an a600 for games? hmmm not a good choise IMHO...
you should have gotten an a1200 for games for these reasons:
1. it has the newer AGA chipset
2. it comes with a 020 as standar, and a 030 accel is cheap, so you could enjoy games. remember that for whdload it is reccommended to have a 030 + MMU + fastram for precash.
you cannot use the quit key in a 68000 cpu, you need at least a 68010 for it to work, meaning that after loading a game if you want to end it, you must reboot...
3. all expansion cards are cheaper and more common than the ones for a600
I am sorry to dissapoint you, but if you only want to play games and you have no sentimental reasons towards the a600, go buy an A1200 and save yourself a lot of trouble...
ofcourse, this is just my 2c, but I think all others will agree with me
