I've played the ME3 demo and I have to say its very enjoyable, the single player was alright, you can only say so much about it, since it was so short, but...the multiplayer I really enjoyed, its like horde mode from Gears of war, the controls are very responsive, the sounds of gunfire are really cool, and on higher difficulties the AI is pretty hard, they will flank you and use grenades fairly effectively. The only thing I didn't like about it was that I don't think they will implement PVP, which would be really cool to be able to able to control your own squad of Cerberus operatives. Also I think they should have a mode where you start from scratch with abilities and have to build up abilities every time you start a new mode and keep taking on hoards going from bronze to silver, then gold hoards. I hope they also have the option to pick a single ability from any class once you level up your character fully or beat the game like they did in the previous ME games, it was great being a soldier and having other abilities and biotics! woot woot but yes its good and I think bioware is going in the right direction, I hope so bad that they make Dragon age 3 they're legacy and make it just as good but hopefully better than origins!!
ps: what are your guys's favorite developers?
