I would exchange the A600 setup for a A500 one. Many games (read almost all ECS/OCS games) were designed with a A500 in mind. WinUAE has a A500 'most common' quickstart config and it has that name for a reason
There are some later games that require more 'horsepower' than a non-expanded A1200, but you will notice that they run slow or not at all.
Also I would really recommend that you use the quickstart configs.
