Someone earlier in the thread said a few people were complaining about the game on HDUK. I do find it very odd that people would spend money without a cursory search though. Hell, I'm browsing shops with my phone out making sure that what I'm buying will be right for me.
Think it might have been better for the image of the game if you had to do the side ops first and then reference the fact that Big Boss has been to that base several times before prior to the Ground Zeroes operation. Eh, it's fun enough for me, but I do hope that there weren't too many confused consumers out there and they were happy with it.
Going to 100% it ASAP so I can get a decent return on it though. Would only have lost £3 if I traded it in now, but I'm still having a lot of fun with it.
