The best way is to get into a time machine and go back to 1993. But before you do, go and get your memory of all modern games wiped. You can't take cash so you'll need to buy silver, gold, or diamonds. When you arrive in 1993 buy an A1200 and plug it into a TV or a 1084s monitor. Play the games as they come out. Get a modem and join a BBS. Buy Apple shares.
If you're interested in pre-AGA Amiga gaming then dial your time circuits to 1987. Buy an A500 with 512kB memory expansion or go for the king A2000.
