Watching Frame Trap, I mirror most of Ben's opinions on Mirror's Edge Catalyst. I've only played the beta, but I liked what I played, and I'm waiting for the game to unlock here in the EU.
So I bought Mirrors Edge catalyst, and I wanted to offer my input into it. Having only played an hour so far (busy yesterday) I like the art direction and the game still feels like it plays the same as the original Mirrors Edge, which is a positive for me. The writing makes me so god damn sad. I walked out of the intro to be greeted by Icarus and right from the start he looks like the biggest fucking tool. Then the writing goes on to flesh him out as a huge fucking tool. I think you can have characters that are like that in a game, but something about him being the first real 'runner' that I saw left a weird taste in my mouth. I can definitely see why Ben said the writing actively detracts from the game (at least I think he said that). Also the default runners vision is like 'Baby's First Mirrors Edge', so I turned it off. Or maybe I accidentally enabled full instead of classic, regardless it wasn't something I really needed.
Aside from the Ubisoft-esque 'you must unlock these radio towers' type open world markers in the game, I actually don't feel like the game suffers as much from being open world. I may change my opinion on that as time changes, but for now I'm okay with the exploration and traversal using the free-running elements.
Oh, and within the first 15 minutes I did a combo that had a finisher that pulled me out to 3rd person and I had a Bosman-style 'Oh no' go through my head. Everything should've stayed in first person after the game finished that intro. Hell, the intro should've stayed in first person. That's one thing I really liked about the first game: almost all scenes were in first person (barring the animated cutscenes).
That's my 2 cents so far with only an hour in. I think I'm going to be glad I purchased it for sure, and the positives will outweigh the negatives. But I feel like there may also be more negatives than the last game just due to the nature of open-world games usually having more 'content' than linear games.
