hmm.. they are essentially the same
Link is just the PG-13 version of Kratos, and
Kratos is the Rated R version of Link
Sony seemed to have created God of War essentially to rival that of Nintendo's Link..
Action/Adventure w/ more slash 'em up/beat 'em up Rated R version
They both have the same defensive and offensive powers, and practically has gone through the same hellacious event and situations... except Link has more items due to his existence as owner of Triforce of Courage. But keep in mind, this doesn't seem to be same Link so he cannot possibly owns or use items in different universes; whereas Kratos seem to exist as the same God of War
In Kratos' world, Link would definitely get his ass whupped
In Link's world, Kratos would get his get his ass beat
