I always put the original Blaster Master on the NES up there.

It had no save capability at all, nor any codes to stop & restart later. When you sit down, you better be ready to do the whole 4+ hours in one playthrough (or just leave the NES on & walk away).

But the kicker was that once you got hit just a few times, you might as well restart. The gun (in person mode) would power down with each hit, and after a few hits, well, you just didn’t have enough ‘oomph’ to kill the bosses. But the power-ups to get the gun were fairly sparse in the first place, so once you got hit, it wasn’t like you could just retrace your steps & power up again.

Mildly interesting, at least to me, I understand it’s been remastered for the Switch. It now has save points AND being hit doesn’t reduce your gun’s power. That would make it a completely different game. I’m be curious to check it out someday. If nothing else, I’m curious to see how much of it I remember. I suspect I can autopilot the first 2 hours, despite it being 40(?) years later.

Maybe 10 or so years ago, was a real push to convert old malls into apartments or low income housing. Turns out it’s not that easy. Those buildings were built with minimal plumbing, just a few public restrooms and limited water service for the food court. There’s just not enough water/sewer to supply more than a small handful of apartments. You’d have to tear up significant portions of the building to run all new plumbing for all the kitchens & bathrooms. And that assumes the underlying city infrastructure that runs to the mall could even support the new water & sewage demands in the first place.

I’ll grant you, it is a cool idea. It’s just not nearly as simple as it sounds.
