Well I played it a bit last night.
I was pretty excited for this, mainly because there have been no new games out for a while and I skipped Revengeance over when it came out on consoles in favor of DmC.
Initially I had issues with my AMD card related to overscan, but that is not MGR specific. Basically despite turning on fullscreen (and the first time the game launched it did so in windowed mode for some reason) I still had black borders around the gameplay area. This is because AMD for some reason decided to keep separate overscan settings for each refresh rate on a given resolution - bu I digress.
The game itself made a shoddy impression at first. I had played the demo so I was familiar with the controls, which I thought were explained a bit better in the demo? Graphically I found the game incredibly subpar. I've just finished playing Assassins Creed Black Flag, and that game looks really great in most areas, and does a decent job of masking the bad parts. Revengeance simply looks dated. I'm not a graphics nazi myself, I mean I enjoy a nice looking game as much as the next dood, but it looks rough. Not sure if this is a performance issues since it happens during cutscenes but it feels like instead of going into cinematic slowdown the game starts dropping heavy frames. Maybe this is an intentional effect? It doesn't look great.
My second issue is with the gameplay itself. As mentioned above I've just come off playing Black Flag. Ironically it is also a game that heavily centers around waiting for enemies to hit you so you can parry and counter attack, albeit it's extremely easy in AC. Being no stranger to character action and having beaten Bayonetta in the past along with the new DmC most recently I don't have any issues with understand the concept of parrying: press toward your opponent and hit light attack. I even figured out you can hold this position if you parry too early, in which case you still block but don't get a chance for a counter. What I'm hoping is that this mechanic starts to grow on you over time because currently, despite knowing what to do, I still manage to somehow miss it half the time, or rather my character seems to wiff air and get hit which is frustrating. Now I realize video games aren't alive so if I'm wiffing on attacks then it's something that I'm not doing correctly rather than Raiden trying to spite me.
Mainly I'm having problems recognizing why some things happen the way they do. Sometimes I parry perfectly and I don't get a chance for a slowdown chop attack. Sometimes I parry and it gives me the option to start chopping them up. I like to use the ninja-run to slide into bad guys which sometimes lets me chop them up and sometimes it counts as just a regular hit. When the mini Geckos(sp?) wind up a kick I've been able to parry it countless times without ever getting a chance to cut him up. I just don't really get it?
Thanks to @hakunin and the video he posted I realized there is a store to buy moves at all - but I had only defeated the first miniboss: the dog with chainsaw tail, so maybe the game just hasn't introduced it yet?
Overall: impressions weren't that favorable for me. I enjoy the ridiculousness, but the fighting feels kinda weird and limited. By limited I mean that unlike other character action titles where in the beginning I feel like I have all this freedom to attack my enemies and learn all these combos, in MGR I feel right from the start, even with the most basic enemy I kind of have to dilly dally, wait to get attacked because attacking myself could lead to someone else attacking me and I'd be locked in mid swing unable to dodge or counter. I'm sure it will all come together with time, it just sucks that they do such a terrible job at showcasing their own combat system.
