With NG3 I assumed it meant RE. Looking at the list again I would put DMC4 and GoW3 up one each. I actually like RE and feel is belongs alongside those other games, I think it has solid fundamentals and weapons.
If you care about story I would suggest playing it first. It’s a bit of a controversial opinion but I don’t like MGS1 nearly as much as 2-4 for many gameplay reasons. If you don’t care about the story then I would say you’re safe to jump into 2. @Redshot
I believe collision damage was reduced to roughly 20% of what it was in GoW2, shifting the combat from collision setups to playing it like a more traditional action game(for me, anyway). I know a lot of people like the Cestus but it, along with the other weapons in the game really pale in comparison to what 2 had to offer imo, the hammer and spear in 2 had great utility(synergy with shatters, stuff like piercing shards for quick knockback and collisions, etc) that I feel the weapons in 3 don’t quite have. All of that being said, still a great game, and of course it has some really epic moments and fights.
Expert? You’re too kind haha. If I placed them it would probably be:
MGS1- A tier(classic game, innovative, great details, fun as hell story, but mechanically its quite weak compared to the others)
MGS2- SSS tier(probably the tightest game in the series, best level design, best alert/caution details, best version of the attack team, and of course the most brutal bosses on EE)
MGS3- SSS tier(Amazing systems, stupid amounts of viable tools and strats, fantastic and varied bosses, really the complete game imo)
MGS4- S tier(best AI, scenarios, and weapons in the series but suffers from pacing issues)
MGS5- B tier(plays very well, tons of stuff to mess around with, loaded with crazy details in series tradition, but is also missing stuff from past games and the open world is mostly a waste)
EDIT: I realize in my post earlier about MGS5 I made it sound like the game is bad or something, it definitely isn’t, it just has a lot of things that bother me and has too many modern elements in it. I also said A tier at first for that game but I think that might be generous.
