Hilariously weird that they are using the Metal Gear franchise name, for a game that looks nothing like Metal gear. They are clearly thinking, 'we have a new IP, it will probably sell like gooseberry fool, lets call it Metal Gear and loosely connect it with that universe because it will sell then'. Which probably won't work at all. Major assumption on my part, but I would love it if the game came out and the MGS stuff was just an afterthought.
Might be good. The stealth gameplay in Phantom Pain was excellent. If it uses much the same systems, but with a bit more immediacy, then I will be interested.
It would be hard to go wrong when their foundation is the core gameplay of MGSV. I'd be surprised if there wasn't at least a few hours of fun to be had with it, especially with friends, but the concept is uninspired as hell.
