yes, it does look like a half-assed port. and it even seems like it plays as more of an interactive movie. if i had a 3DS i wouldn't buy this, despite my love for the MG series.Maybe because based on everything we've seen, it looks like some half-assed port compared to the Naked Snake demo he showed before.
but kojima says it's remade from the ground up. that's more solid than big ass babies whining that it isn't a remake, and it's just a port.
wait until the game is released and then rip the rom apart if/when it gets dumped.
