Suicide Squad is finally here and despite the massive hate boner the internet has for it I can confidently say after 5 hours that it's... fine.
It's too early for any final verdict but I am enjoying it so far. It has all the things I liked about the Arkham games such as codex entries that help to flesh out the world and characters, the narrative is interesting and I like the characters, though I wish they'd gone with fat Waller. Too soon to comment on the live service stuff but it's fairly unobtrusive early on.
When playing single player your squad mates are controlled by AI which do not require babysitting and are generally helpful but they can't do any context-sensitive stuff where you have to run up to something and hit X.
Missions are pretty basic so far, mostly killing enemies, defending objectives, or rescuing people. But the missions themselves are pretty quick and don't overstay their welcome. The early story missions were great but no clue if we'll see more missions like those but I hope we do.
Combat is pretty solid though nothing amazing. Each character has their own traversal techniques which do have a bit of a learning curve. You can switch characters whenever you want and some characters will even get exp boosts on some missions so the game does encourage you to switch between them though nothing is stopping you from just sticking with one.
You can pause in single-player player which I am very grateful for.
The performance is decent, I'm playing on a 4090 with everything set to high and ray tracing off. I'm able to maintain a solid 60fps but can't get anywhere near 120fps. The lack of DLSS or FSR definitely hurt. Would be interested to see how people are doing on lower-end hardware.
Overall I am pretty happy with the game, we'll see if my opinion changes as I progress but I don't have any serious complaints so far.
