Either should work (hopefully). Mega tends to be unreliable with bigger downloads (not sure if it's an issue only I have or a general one) but for me bigger mega downloads just tend to stop partway through for no reason. Tried downloading the game a total of 5 times now between yesterday and today and I never got to 2gb of the overall download. My internet does work tho so no clue why the download keeps dying. Just gonna have to wait until you get a mirror ready.
