Played the demo up until you reach the city after your class selection by myself. Felt like I wanted more from it. The intro piece after your team lands made me like the world as what it was, somewhat lush with a green landscape, then after that it turned into mush. Hopefully you get to return to some areas like that, and not be some Rage type of color palette.
Gameplay wise, yeah the game really doesn't pick up until you have your powers. Its a nice short cooldown to get you running and gunning. I definitely should have not picked Pyro and went with something else. I think there is some weird sensitivity issues you gotta battle with at first to get the flow of the gunplay, but there is still some more that can be done with it. Am I crazy in thinking there is even aim acceleration on console? And sometimes my character will fail to go into cover. I read yesterday in this thread someone stating you need to point the reticle towards the thing you are trying to cover under, so I might try that later.
Then there is the jarring cutscenes. Holy crap. The fade to black to a cutscene, to fade again, to walk to another cutscene was just why. It needs to be more seamless than that. Its like the characters cannot animate or emote unless they are in a cutscene, it just takes me out of it. I just put the controller down and wait for that fade again before lifting the controller. It takes away the immersion of playing completely.
After a few hours I went back to join my friend who just gained his powers and we did a few mission/quests and doing some combo moves together was pretty excellent. It definitely enhances the experience to play with someone else, but I still feel like I need more out of the game. I didn't go into it with much knowledge of the game itself, but ultimately came out of it like eh. I don't know if I'll be picking it up when it drops.
