Sounds a little like: »The game doesn't properly run on your computer? Go buy yourself some new hardware! Signed: The programmers.«
Yes, exactly.
It also doesn't work on your iPod, on your PSX, on your toaster's program selector and on your fridge's temperature display. Oh, and it doesn't work on in-flight entertainment monitors in airplanes either... what a shit product this is!
So yes, go and buy the frikkin' microsoft mouse for $2.99.
I believe the point was: It's not exactly the most wise way to assume things, that never before were a necessity for playing the same game. At least I'm not aware of the need of a middle mouse button in (Open)Xcom. So why force this need?
Because the left and
also right button clicks are already taken for other actions, simple as that.
PS: I wanted to add shift+right_click today as alternative to middle click.... because I myself am doing this on laptop without a mouse... but after such feedback, I really won't... thank you very much.
PS2: OXCE+ was never a necessity, go back to vanilla and stop whining here. Howgh.
