I had a post ready and then closed the tab on accident :( Some of these ideas are stolen but I could not think of these frame 1
So many of these are so split that I genuinely can't decide some of these, at least not right now. I put some potential sets near the bottom.
- beatmania IIDX (latest version, live service)
- Another live service rhythm game (SDVX, DDR, StepmaniaX, or maimai DX)
- A fighting game in Japanese cabs (MvC2, CvS2, 3rd Strike, or MBAACC if I could get people to play it)
- A bullet hell (NOISZ Arc:Coda or Mushihimesama Futari)
- Tetris TGM3 (alternatively, either TGM2TAP+ or Tetris Dekaris. WMMT from the grab bag would also fit here)
- Another live service title (KR Ganba Legends, SDBH, Pokemon Mezastar, Derby Owner's Club, WMMT, Killer Queen, or Red Earth. WCCF Footista could also be fun, but is a dead game. I'd also fuck with a straight up racing sim there as opposed to WMMT but WMMT is just as interesting in a different way)
- Tempest (alternatively, Ms. Pacman or a game from the grab bag)
If I had to choose a set right now (THIS IS MY DEFINITIVE ANSWER): IIDX, maimai DX, MBAACC, NOISZ, TGM3, WMMT/racing sim, Tempest
If I expected to be playing a lot of games with guests: IIDX, StepmaniaX, CvS2, NOISZ, WMMT, Killer Queen, Tempest
If friends from the tourney community are coming over: IIDX, DDR, MvC2, Mushihimesama, WMMT, Ganba Legends, Red Earth
I don't know NeoGeo very well, if at all, but I do know a King of Fighters title will be there for sure.
