There’s something about the Amiga era font and graphic style that I love and I always feel is unique to the Amiga but had trouble pinning it down to a particular developer or graphics artist. Ruff n Tumble is a good example, with like chunky futuristic font, the strong gradients all over everything and even the colours. It’s not common to all games though.
Yeah, I agree. I also had C64 and DOS, and while both had tons of games, the Amiga was a bit different. In a way the Amiga was kind of a stronger predecessor to e. g. Xbox or similar variants (there were also TV console games, of course, and I played them too, so these may be called more appropriately the forefront-runner towards Xbox and other consoles, but I feel that the Amiga was kind of positioned in two places here, whereas DOS was more on the application-side, business-side, than games side, even though there were also many good DOS games. Master of Orion 1 is one of my all-time favourites; Master of Orion 2 extended many things, but the gameplay also got slower and I did not like that. I loved the fast play style that was possible, also in other games, civilization 1, simcity 1 and so forth).

Jim Sachs was one of the early masters. The Wikipedia article about him does not do him justice: https://en.wikipedia.org/wiki/James_D._Sachs
One amazing thing was that even after the Amiga became available, he continued simultaneously making great art on the C-64.
