There's a lot of singleplayer stuff and genre stuff I wish continued on (Freedom Force, Freedom Fighters, The Warriors, AKI style wrestling [cmon AEW!] to name a few) but I'll answer this in the multiplayer or live online sense.
This one is probably premature and all, and it's kind of insane I think this given my reaction when the game was about to and did release... but I miss Hitman 2016's episodic model and focus on live. 2 is a great game too but surprisingly it was worse for that. I say that as a long time series fan who scoffed at the episodic release and live game features at first.
I know they still do live stuff and some DLC but it's not the same.
Maybe for 3? I know 2 was similar so the response will be diminished but it didn't seem as successful to me.
Also really miss all that GB coverage. It was a shame they hardly did anything with 2 (and what they did do was great). Maybe it was being tired of that, or the non episodic release hurt that idea, or both.
Ninja Gaiden Black / Sigma, etc. I feel like the character action space is missing it.
If we are talking single player stuff, agreed. There is nothing that technical in the space. I think most games have tried to move to simple inputs and depth more in systems and upgrades vs basically having it all like NG at its height.
Problem there though is that Team Ninja still exists, they just are not good anymore lol. But no character action has grabbed me nearly as much as NG and Black since then.
