it's still missing a few Seihou game, LNB, and many shot type rankings. I'm undecided on whether or not to include LNNs and ExNNs due to them being inherently luck dependent. Fangames might also be added at some point but I'm not sure of that either. It's also entirely possible that these rankings will change at some point.
) that ranks arcade shmup difficulty. The list works on a scale of 0-50, with higher numbers being harder. I tried to make this list equivalent to the Japanese STG Wiki one, so for example a 20 on that list would be about the same as a 20 on this list. Games with no number are equal to the number of the game above.
