I'm having a lot of fun with Metal Gear Solid V: The Phantom Pain. However, I might be a bit biased because I'm a fan of the MGS series (most of its games anyway) and I enjoy most stealth games.
I was in the same boat, to be honest. I got Ground Zeroes but I didn't really enjoy it. It felt a bit repetitive and while it gave you an open environment to play in, it still felt a bit restrictive and at times difficult.
With the Phantom Pain, the environment is absolutely huge. Much bigger than Ground Zeroes. In Phantom Pain you have two locations to go to, Afghanistan and Africa (although I haven't unlocked the latter yet). Both areas have heaps of sub areas inside it, but it's all open. The open environment feels a lot less restrictive than the environment of Ground Zeroes, to me it feels like there's a bit more freedom.
I like Phantom Pain because it has a wide variety of missions. The game does have a story, but it focuses more so on the game play. Under going missions, whether it's story or side-ops missions, it's cool because you get dropped off via chopper to a landing location of your choice, you can pick pretty much whatever mission you want to do too, providing you've unlocked it. You can even choose when to be deployed, e.g. in the morning, at night etc. I prefer to do night time missions. There's a really cool feeling about going into a base at night and rescuing your captured comrades.
You can also unlock a lot of new stuff through upgrading Mother Base. So you can upgrade your weapons/equipment, items, your "buddies" and you can upgrade Mother Base in general. So there's a bit of management style stuff, I suppose.
"TL;DR" - I didn't really like Ground Zeroes either, but I'm really enjoying Phantom Pain. I think you will too.
R...just read it you lazy bastard.
