Solid Gold is a really nice game.
Suggestions for two basic platforms to make games for:
1. A500/A600 with 1 MB chip, OCS.
2. A500/A600/A1200 with 2 MB chip, 2 MB fast, 68020 and OCS.
Example configurations for number 2:

A600 + ACA620 + chipmem expansion
A1200 + fastmem expansion
Amiga Reloaded + ACA12xx
