What's interesting to me is the "kill screen" in Tetris is (apparently?) at a variable point in play.
So, this was the first person to encounter the "bug" (hardware limitation). But, future players may try to hit that point faster, with a lower/higher score, or other combinations of game state to beat the game in a "better" (more interesting) way.
I think most "serious" Tetris players can get to 30 easily in a short amount of time, right? Like 15-20 minutes? It'd be hard to think of that as a legitimate "ending."
Whereas a run to level 100+ or whatever for this kill screen is a major achievement. Took people 30+ years to get there.
I don't know, though. It's all subjective. If you want to think of a hypothetical lvl 30 crash as a "kill screen" or "ending" then hey... go for it.
