“When I see this [Super Mario Bros.] so clearly, it’s a little embarrassing. Back then, with tube televisions, it was a little blurrier and the images weren’t quite so sharp. The places where we tried to fudge it a bit really stand out! Whenever we work on the re-release of an old game and I feel like something isn’t right, I’ll ask someone, “It wasn’t like this, was it?” but most of the time they tell me, “Yeah, it was like that.” I think that if I were making that game today, I would fix it, but in a way those rough places are a part of the game and even well-received.” - Shigeru Miyamoto
Part of the game’s charm are those rough areas. Hell, I still think the game looks great today. It’s an iconic look and a classic design. Nothing wrong with that, in my opinion.
