All the crap your whining about is optional. You can essentially just play through the story and enjoy it just fine nor have to even talk to Paz. Great thing about PW was how you could play it as you want.
Course it seems like everything makes you want to stab yourself, so it's hard to say how anything can please you. Think you enjoy the pain really
Well.....for once I kind of agree with him
I mean even if you do what you said, and just play through purely the mandatory stuff, then what?
There's no difficulty levels and because of how weapon leveling works you're completely overpowered for everything you just played by the end making any attempt at a replay pretty pointless
Snake's moveset is drastically simplified, and the moves he does have are extremely overpowered in the context of the game around him, making the difficulty level of the game extremely low.(at least for all sneaking missions. With hold up, smoke grenades and chain CQC S ranking every sneaking mission is an effortless task. The vehicle bosses are a different beast entirely and I won't get into how I feel about those.)
I think Peace Walker was a fun game that accomplished what it set out to do.(A more playable portable metal gear than PO that appealed to the younger Monster Hunter generation in japan)
but it by far has the least to offer from a gameplay perspective than any other Kojima directed Metal Gear game.(In terms of balance and compelling content) I don't think it holds a candle to any of the mainline entries frankly.
The only thing I'd like them to take away from PW and develop further is Co-Ops, a concept only half baked in PW because they chose to balance every mission around single player as to not alienate players in the west.(Co-op missions in huge open environments like the ones promised in Ground Zeroes sounds like itd be pretty amazing)
