THere are downsides, had they put maybe 3 minutes more thought into the story it could have been far far better and less cheesy and irritating.
Its a big map and partially as LeJosh said its samey, even though theres actually a lot of locations, mostly because its the same thing in each location and because the game is so verticle and you don't run through towns and airports and compound A, B and C, from above the layout of the base and how it looks from the ground has almost no effect on gameplay.
In other FPS's a wide open airport heavily manned would have a very different feel to a dense town area, but a lot of that dissappears when you're floating over the top launching rockets at everyone.
Autolock, could have done without it, would have sucked on consoles without it due to the type of game it was.
Sometimes I think its brilliant, sometimes I think its a lazy pile of tripe in terms of gameplay.
Engine though is just fantastic, quick travel to other side of the map, instant basically, runs fast with all settings on high, looks pretty damn good. I've never seen a game so big, with a map so vast load so quickly, frankly you rarely see a tiny game with a tiny map load so fast
