The Ghost & Goblins arcade games series consists of about 3 games but what the heck I thought of a fourth one. Wolfenstein 3D is pretty challenging, especially since you have to work with the basic controls you have: moving and shooting. Nothing else. And since that means you have to be resourceful and riskily bait enemies right to where you want them and most often stunlock the heck out of them, it's pretty darn risky gameplay. Have you ever tried to stunlock a Shutztaffel? You'd be scared to heck he'd rip through you if you don't mash that CTRL button fast enough, because he actually can.
