Side note:
Kind of surprised that no one opened a thread regarding the pre-review of the game by Jeux Video Magazine. There are a couple of noticeable complains there:
-Players need to focus on Mother Base building from early on, to avoid getting stuck on missions later, that require specialized items.
Which also means, you can't use any weapon aside of the Tranquilizer gun until you have collected enough personnel for R&D. And apparently that takes a lot of missions.
-There isn't a lot of story exposition, at least during the first 30 missions. Few cutscenes (although well done, apparently).
Will be interesting to see if that turns out true.
