Awwwwyeah Robotron! No joke, Robotron 64 is my favourite title for the N64. Really, really wanted Assault Android Cactus to be similar but its weird battery system had you playing that game in a very different way than how I prefered to play Robotron.
I checked out some game play videos of Robotron 64 last night and it looked like a lot of fun.
Robotron: 2084 felt like a successor to Wizard of Wor and Bezerk, all three of which gave off a strong horror vibe. Wizard of Wor was more of a fantasy/sci-fi mash-up, but Robotron and Bezerk were dystopian obviously. WoWand Bezerk had great voice synthesizer work which was a big part of creating that atmosphere. Robotron added that fast paced gameplay with great controls.
Midway Arcade has an interesting UI and tries to capture the cacophony of sounds a room full of arcade cabinets makes. I definitively take the time to move through the virtual space to listen to the hum rather than just accessing the games directly from the menu. I would love to see what they could do with a Switch. This is probably the answer to Kairon's question: arcade collections. A Midway Arcade, or anything similar, that has individual save states for each game would get really excited.
