See, I wasn't a fan of Peace Walker, I found it too disjointed, apart from a couple of missions that didn't allow him, there was no reason ever to use anyone other than Snake, 90% of the weaponry was useless, I think I got through the game using maybe 3 or 4 guns, I liked the idea of growing my base but... Well it's just an idea, you barely get anything for your work. I dunno, I just didn't see what was so great, still, if you had fun with it then that's the main thing. Ground Zeroes, however, I absolutely agree with you on, I've put almost 8 hours into that game and I've only got 40% of max completion so the idea that it's too short is a tad baffling. Still, the gameplay is solid, the story is a great way to set up The Phantom Pain and it's put MGS back on my radar as #1 game to look forward to... Maybe Persona 5 could beat it, we'll wait and see.
