Twin Snakes made a bit of a mess of the original MGS, imo. I was hoping they'd have done some digital trickery to get a HD version, but I can live with this.
Was going to buy the HD Collection for Vita, but might just hold off and get this. Already got 1 on PS1; 2 & 3 on the PS2 and a copy of 4, but what the heck... depends on the price I suppose.
