You see, even though we've seen trailer after trailer of Metal Gear Solid 4, we've yet to see much concerning actual gameplay. An aging Snake taking on armies of mechs alone? Not likely. Many gameplay elements are completely unheard of -- this may be a reason why. What do you guys think? Is the PSP game a sort of test for how loyal enthusiasts react to gameplay changes that may appear in the PS3 title? It's an interesting idea, but at the same time, no one thought that Snake would battle with cards via Ac!d in future games.
