Wow, so many great looking games to add to the list in here!
I'll just add one that hasn't been mentioned yet, hopefully not because people have forgotten about it again due to its delay from 2016:
80's Overdrive.
The devs were interviewed by
Nintendo Life in September about their radio silence and while they could not give a concrete release date, they did break down their development cycle and mentioned that they were finishing up. Hopefully the end result will reflect their hard work and commitment to not "publish a complete crap." The video shown with the NL interview does look promising imo.
Fake edit:
This reminds me: what happened to that one Kickstarted retro indie sidescrolling action game that had some people up in arms when they completely changed the art style from something akin to 8-bit Shatterhand to a more 16-bit aesthetic? I wish I remembered its name... Edit: ah, found it, it was called
Steel Assault and apparently they have a beta build out for backers. Any impressions? Not many people seem to be talking about this one.
Edit: Another thing that popped in my head: why do I never hear anyone wish for a Switch version of
Rain World (assuming that that is a good way to measure indie staying power)? That game seems largely forgotten despite some good reviews. I never played it but it always looked interesting to me due to its moody world, slower pace and deviation from typical platforming / survival games.
