They're the same awards BOTW, Half Life, The Witcher 3 and Mario Galaxy won... I don't quite understand why people scoff at rewards when a PlayStation exclusive wins them.
DMCV was good but had its problems, V combat was flat, the scenery got very repetitive and the game has little to offer beyond combat.
I found GOW combat far mor tactical and precise, it built you up to the Valkyrie queen and either your reactions were sharp as a scalpol or you were dead in little over a second. Then you had a great introduction to Norse mythology , beautiful and varied worlds, epic boss battles, collectables, puzzles, armor, metroidvania level design etc.
It's ok if you didn't like it but it beat RDR2 and read dead 2 had all that Rockstar hype and expectation... It wouldn't do that if it was just an 'ok hack and slash'.
