Compared to the original this game is less organic. Examples; Only one piece of equipment per soldier, enemy units never move until discovered and you can't place bases wherever you want. Similarly, single player switches from battlefield to squad feel. The game's squad focus and less organicness create advantages such as much less micromanagement, class abilities and maybe mission variety. Game gives up all pretenses of scary in favor of more epic. The slow mo overwatch animations and burned out crash site forests succeed at being epic flavored. 8/10 atm I will get back with more details later.
Update: Only one micromanagement/UI issue; when just moving through map with no aliens to shoot I am forced to go through the whole team to set overwatch or hunker down after non-dash move. Automatically set to one of these on end turn pls. Just one fault puts this UI far above that of most strategy games. Strategy ends a bit simplified as it often boils down to staying close to squadmates, moving slowly and focusing all fire to kill off any alien foolish enough to wander into view.
