I was top 1000 for a while in the base-invasion mode of MGSV in the EU. That mode was basically a low-budget little tacked-on multiplayer that kept the core-gameplay and I spent hundreds of hours on it.

MGSV Metal Gear Online (the _other_ tacked-on multiplayer) was also great, but very unreliable netcode made it frustrating.

I wish someone would just take that game engine and make another good game on it. I _almost_ bought metal gear survive on the engine alone, that is how good it is.
