I never played the first MGO, but I spent a lot of time with the MGS4 incarnation. I had pretty much stopped playing obsessively by the time the last expansion came out, but man I had so much fun with that game. It's a shame that there's a widespread perception that no one played MGO (almost to the point that I was going to email the bombcrew to answer their question of ''Who wants another MGO''...I ended up deciding I really didn't care that much if they want to dismiss it). It really did allow you to take the freedom of action in the main game and go up against people who were all playing their own way. It helped too that the community was pretty tight, probably as a result of the ridiculous hurdles Konami made you go through to play and the fact that the PS4 was still really expensive back then; the people that were playing were really into it.
My biggest request is that they keep the reward shop updates in the English release generally close to the Japanese shop updates. Other than that as long as people are having fun sneaking around in boxes I think I'll be happy. Also singing. I'll be happy as long as I can sing.
