Ive fell out of love with the MGS games personally.
I suppose if you have the patience to sit through the tedious cut scenes (if you dont get Deep Vein Thrombosis)
Then when you get past all that is a decent game, i prefer splinter cell personally because i find it more fun, realistic, addictive and just overall a much better game.
The gameplay in MGS is fairly simple, i played the last game for half a day and got bored.. maybe its just not for me.
First person though might just get me interested again
We shall see.. does look f'n awesome though i admit.
