For me it’s first person puzzle games. I can think of maybe a dozen off the top of my head that came out in the last decade. I especially enjoy when they’re open world. The ability to just quit a puzzle that’s stumped you and go try something else for a little bit is incredibly refreshing.
As for the antigrav racers you mentioned, have you checked out BallisticNG? It leans more towards Wipeout than F-Zero, but even as a huge GX fan (and looking forward to Aero GPX myself) I’ve really enjoyed it. I believe it does have splitscreen as well, though I haven’t tried it personally.
It couldn’t hurt to try it out, but I always liked F-Zero more than Wipeout. At least it looks to be as fast as F-Zero.
It’s got a variety of speed settings that increase in difficulty, and it absolutely gets fast enough for anyone lol. I like it a lot more than the actual wipeout games I’ve tried even though its mechanics are more styled after that.
