The most important thing at the core of any of these games is that the missions, ground combat and tactical gameplay is fun, if you get that right the game will be fine. I just hope we get a bigger selection of enemies than X1 and that we also get more varied AI with those enemies to fight against. Evolution is fine. Essentially this is a chance to take what worked with X1 and just make an improved version of that. The graphics and rotatable camera look like big improvements, I just hope there will be a new forces to fight against and the AI will be unpredictable and put up a good challenge and behave well - and that the game will be replayable due to that.
