if kojima redid metal gear and metal gear 2 with the mgs4 engine i would be blown away
being able to kill big boss with a spray can and lighter fluid in hd &)
I've been saying that if he really wanted to make more bank,the best idea would be to Redo those games.Especially since the original versions have very limited diolouge.If they were ever to be released like that,it would basically be 2 entirely new games.
The best thing about it would be that he could redo each one to its full potential,and release them at separate times,like in a 2 year span.
It seems like the only logical option since he pretty much ended the series with 4,and I doubt rising will turn into its own series (although i could be wrong about that).
