After watching a bit of a stream of this game last night, I'm genuinely tempted to go in for the Season Pass. Haven't had that since The Last Of Us's Season Pass.
This game looks like it will be a real achievement in terms of fidelity and level design. There were bits where it looked like the person was playing a pre-rendered CGI Batman movie. And the extent to which he could explore crannies of the city, approach enemies and encounters from different angles, was staggering. At one point I also swear there were more than 60 individuals on screen; pedestrians and criminals walking about and interacting, almost like GTA. Without losing the fidelity. It looked amazing and I didn't expect that at all.
I get the feeling it may be a gameworld we want to keep spending time in well after the credits roll, so a Season Pass may look like a worthwhile purchase. That's taking for granted that the content is up to scratch.
