I actually just finally started playing through MGS5 and I'm loving it, but now that this is 50% off I'm definitely going to bite on it too and add it to the queue.
Out of curiosity, you playing with kb+m or controller? I'm doing just great with MGS5 using kb+m when I thought I'd be forced into using a gamepad, wondering if this game is similar.
I've used KBM for this with no problems. Same for MGS5.
