MK and KOF are similar enough to SF in my eyes, but it's a pretty monkeycheese list anyways lol
Why did you list four different players? The advantage with round robin is that you get to judge Apologyman vs Aris, Apologyman vs Leffen, Apologyman vs Tom Brady in Smash, then the same matchups again in KOF, Persona, etc. You need to do well in everything in theory.
The issue with mystery game format is that you are unable to prepare for it beforehand. By having a preset list you can see players at their best across multiple formats.
