woow you lot know how to confuse a poor "newbie" listen here sharpie:
if you want ONLY the oldest games get an A500 1.3rom with some extras (easy to find on ebay.com/amibench.org just follow the auctions a while and see what things go for so you dont get ripped off) extra hd + ram etc is also very nice to have
IF you also want the newer games + some of the same games you can find on A500 only with better gfx etc get an A1200 also (if it were me and i only wanted to get into gaming again id get both) just make sure you get an Commodore A1200 NOT Escom A1200! HD ram cpu upgrade etc are nice things idealy get a 030 card! if you get all this (should not be that hard to find at an ok price) you will be able to run at least 90% of the games you can find on Amiga.
