Adam, you said I could do this, so I've decided I'm going to resurrect damned threads from the dead to guess their references.
OK, so the title of the arcade game looks to be a mash-up of Double Dragon and Bad Dudes Vs. DragonNinja, as do the characters, as they're both wearing singlets, one black but the other red, along with bandanas. The gameplay looks as though it's from the arcade Ninja Gaiden while the background looks as though it's from Castlevania. The werewolf in the corner has the outline of TeenWolf while it's clothes are that of Back To The Future, so Michael J. Fox 1985. How good did I do?
