Sucks you're not enjoying it. What changes make it worse?
The controls and general gameplay feel a lot worse to me. The placement of buttons and actions just feels off and I keep pressing the wrong button in the middle of combat and dying as a result. Stealth doesn't seem as good either. The enemy AI appears worse in WD2, they can just be so dumb so often its very annoying. I try to complete missions by stealth as much as I can, as that's what it feels like Marcus would be doing, but for a lot of missions just going in and shooting everyone is so much easier. Stealth takes way too long in comparison and often doesn't work because you haven't got the right upgrade from the skill tree to get through that door over there, and other things like that. So you're driven to shooting everyone much more than the first game, yet gunplay is noticeably worse.
The missions are ridiculously repetitive so far and I'm pretty bored of it already. The vast majority of missions so far have been infiltrate this place and hack this particular panel. Its getting so boring.
The puzzles seem to be pretty much exactly the same but appear less frequently than the first game, which is sad because I quite like them.
The first game had a great open world with lots of different side missions that felt fun to complete but with WD2 the world seems so empty and bland so far. The time trials look fun but driving in WD2 feels so bad, especially after playing so much GTAV that I can't enjoy them.
Also while most people like the cast of WD2 I... don't, to be honest. I don't particularly like Marcus or any of the gang to be honest. They don't seem like the kind of people you would expect hackers to be and they can be really annoying with the way they talk sometimes. Also it bugs me that followers are the XP system in this game, because you gain followers for doing some really weird stuff. Like why would 20,000 people start following dedsec because I went and talked to someone in a cafe?
That being said, the hacking in WD2 is a lot better. There's so many more options to hack and I like how that adds to the stealth experience.
