1980s 2D had the same “every machine sucks uniquely” vibe as 1990s 3D. If the same game on two platforms looked remotely similar then someone busted their hump getting it right. By default, you were getting a game that looked and sounded as good as this system could manage, rather than being a smoothed-over downgrade of some canonical example.
Ironically it wasn’t always a great era for pick-up-and-play-ability. Late-70s games were so limited that arcade sensibilities were nearly the only thing possible, and even text-centric computer games lacked the memory to bore you with backstory. By the late 80s they could push the early inklings of an unskippable cutscene and a tutorial level. Dunno if that’s better than ZX Spectrum games getting mercilessly sink-or-swim.
Coincidentally that arcade vibe also matches the late 90s: it’s how most Dreamcast games feel.
