I can think of a handful of games that, despite being games that I’ve enjoyed, never really became part of a “genre”. Do you have any like this, and if so, which?
Are they games that you’d like to see another entrant to the genre to? Would you recommend the original game as one to keep playing?
Ahh yes, definitely. I should have said that isn’t strictly a traditional shmup. Bangai O definitely has many elements of shmups, but the level design and many of the mechanics are quite unique to it.
