Just started watching the Punisher series on netflix and it just amazes me that I've never even heard of anyone trying to do this. I'd imagine something like a cross between MGS the Phantom Pain, Hitman, and GTA, and Rainbow Six. It could easily be one of the best games ever. An open city, you can walk in on crimes happening and stop them or do the story missions which are more similar to Hitman series. It would NEED to have more realistic weapons and 1 or 2 shot kills. Also environmental deaths and CQC. Also microtransactions are regulated to skins.
