Considering I still boot up the game every month or so just to load my saved game at the Atrium and climb it a couple times, yeah, I'd like a sequel to it. Everything about the game was a good idea, except the Esurance-style cutscenes that look like they were made by some interns probably with Flash.
I guess I was the only person who thought the combat was kinda cool. I liked the animations and the concept of disarming and not using weapons (went through the game with no guns on the first playthrough, I'm sure plenty of others did the same). I'll admit trying to take out 20 guys at once in direct combat caused the game to bog down, and being two or three-shot by those larger belt-fed machine-gun troopers was tough, but I appreciated the challenge.
Obviously I'd like more free-running, a more open city-roam mode. I kinda like sandbox games, and it's not like ME needs to be a sandbox game, but with a giant city, it seems as if it would fit well to have a mode where you can just run around the city between levels or completing freelance assignments or something...
The game had some real sweet environments, I loved the sewer levels, the atrium area, the warehouse level, loved searching for the hidden packages, it was just a pretty cool world. However, running around maze-like corridors would get tiring no matter what pretty color they put on the walls (though I do love those pretty colors :3). I think the larger levels should have been more open, like the crane jump level, for example. I appreciate the scripted events, but I just wish they had more than a few ways to approach problems. They really need to maintain that kind of variety and add more to it in the sequel.
Honestly, the game's length felt good to me. I know everyone complains about it being too short, but it seems like as soon as I thought the concept of running around and pressing spacebar was getting a little old, the game had its conclusion. In the sequel, maybe they can add more to running around, jumping, rolling, sliding, so it doesn't feel so automatic ("press shift to do something cool as you land"). I liked the controls, I liked the camera, I liked the difficulty, I was able to tolerate the story/characters, the disarm timing was kinda stupid, and making a QTE-based boss that's just "hit disarm correctly 3 times" is just a pointless, forced boss. I guess it's better than it being a cutscene, right?
Anyway, if anything, ME could be more polished with more "stuff" or "meat" in the game. That's really the common complaint. That and the combat being "horrible." I don't think it was horrible. I think it was unfair, because it pulled you away from what made the game so fantastic. If you want to run around, there should be minimal combat. If you want more direct combat, you should be playing a different game. It's almost as if DICE made some beautiful free-running game and EA was afraid no one would buy it so they insisted that DICE put guns in it. To me, the combat felt forced at first, sort of like an afterthought added on in an attempt to appease the CoD generation, but that said, the way the game's movement is, I can't imagine playing it with thumbsticks anyway.
CoD and Halo work with them because the movement is slower and the games are more about aiming. ME required a lot of vertical movement and quick mouse-flicks, and it would just be a lot tougher to experience the game the way it was "meant to be played" on a platform other than the PC. That's just how it was designed. Not trying to bash any platform, but the way the controls, camera, and movement worked, it just seemed like the best "feel" on PC. They need to find a balance there that allows the player to make acrobatic movements with ease yet still make the player feel skilled and quick and awesome.
Either way, the game had a LOT of potential, and I'm surprised that they went the direction that they took with it (MGS style "hide in a truck" mission? Save your sister? A cast of...maybe 5 characters, most if not all of which are forgettable? Great atrium-climb followed by a stupid snipe of a convoy followed by a stupid-yet-"epic" conflict as you try to get to the ground floor and get out, directly confronting about 20 enemies...?).
I hope the sequel addresses most of the issues we have with the game and refines everything we love about it, with more content, more development, and more Mirror's Edge, instead of linear-shooter #984.
