In fact I'd actively avoid the Platinum version because the cover art looks atrocious.
They also updated it a while back so now it does one large install at the start instead of lots of smaller ones throughout.
Don't forget about the MGS HD Collection, if you haven't played those already.
Surely this is the version you want?...

Might have to do it all over again before Phantom Pain comes out.
