The one above solid normal, forgot its name, me and my bros wanted a challenge (MSG isnt a solo game for me, but a cherished family tradition), so we went with that first. Was tough, but in lots of parts we messed around, didnt play so sneaky and hiding game at times, except the jungle and snow parts, those were FUN to sneak in.
Yeah, I'm not a fan of replaying games at all, especially MGS like games where the story is the main fun (this one had one complicated storyline), but wanted to try a harder difficulty level while sneaking around all the time, 24/7.
