Quote from blackdogNo i only tried the very first one on PC, way after I got used to Splinter Cell and haven't been able to get to the elevator at the beginning of the game, even though I had done all the training rooms :$
I know that MGS has all these little bits like the box/barrel… but still I find incomprehensible this balloon mechanic: what does it do, what's the purpose? Score?
I can understand and appreciate the lol factor of catapulting some guy down a cliff with the decoy-mine, but you cannot justify that guards standing like 20m away don't react to that.
Unless I'm missing something the most obvious use of the balloon is that it allows you to get rid of enemy bodies, which is always one of the main priorities in an MGS game considering that one being spotted results in serious trouble. I'm assuming that it's somehow limited in terms of uses to prevent the game becoming too easy, though.
I think the original MGS has aged pretty badly because the camera makes it incredibly difficult to play properly (the GameCube-only remake of MGS1 is far better because it allows first-person aiming like the later games), but I would say that upon release every MGS game has had absolutely excellent gameplay mechanics and indeed that is one of the main reasons why the series is consistently so popular. Splinter Cell and Hitman might be good but I've always found them significantly behind MGS in terms of fun stealth that makes you feel empowered yet vulnerable.
I don't know how MGS5 will pan out, but I've personally always loved the UI in the previous MGS games. I didn't find MGS4's UI cluttered at all, all you had on screen were your health/stamina, a mini-map if you had that tool enabled, and icons showing which gadget/weapon you had equipped (nothing would appear otherwise). MGS always shows you the basics in a really elegant way IMO.
