I can see where you're coming from and I agree at times it feels like it's being used for the marketing since it's easier to say, using the article as an example, "Bullfrog-like". They could have taken an extra moment to be a bit more descriptive, such as with your example, and say “Management Sim inspired by Theme Hospital/Bullfrog”, for people who may not be familiar with "Theme Hospital" or a Bullfrog game.

Just to circle back to your initial comment, "I got to the word “Bullfroglike” and stopped reading", I can definitely see where you are coming from, but I did disagree with your approach.

I also just wanted to add that I hope this isn't taken as an attack upon yourself.

I do like the alliteration for "Boomer Shooter" but I don't think it's the right demographic xD. I think it's still somewhat common, but I also don't think it's as mainstream as say your Battlefield or CoD.

RetroSlayer FPS? I have no idea, lol
