MGS 4 has a 80%.
That means to even out that one, it needs 7 perfect scores, to be on level with OoT.
MGS has 4 80%, it needs more than 25 perfect scores to be on level with OoT.
GTA IV Ps3 had about 30 perfect scores.
That means that the rest of MGS 4's scores would have to even at 9.7. That's though.
4 80% has already destroyed MGS 4's changes. GTA IV Ps3 only had 1 score below 90%, at 88%.
