Best game of all time ? No. The other MGS games are better.
Its an extremely awesomesauce game (my 2nd favourite of this gen), but it isn't as good as the other MGS games. The gameplay made big progress, but the multiple setting scenario was a bit meh.
I loved the fact that against, all odds, you infiltrate a single facility/complex and complete your mission in MGS 1,2,3. In that case MGS4 was all over the place.
I loved the whole one guy in the middle of the battlefield aspect that sorta replaced the single setting thing, but that was only in the first two acts for some reason.
That and Act 3 was,
Follow some dude, watch a big ass cutscene, (awesome) vehicle section, boss fight, another big ass cutscene.
Plus, the Drebin point system could be abused to get ammo easily... You could keep buying anti-tank missles and destroy your enemies when you run out of ammo.
If those issues weren't there, it would have been the perfect game, imo.
It (along with GoW 3) was the reason I bought a PS3 over a 360 and it most definitely didn't disappoint, but it wasn't as good as the other MGS games despite the advancements in gameplay and controls.
However, it did end the series storyline in an awesome way and I am happy about that. Bravo Kojima ! Happy birthday MGS4 !
