Best God of War game. Nice storytelling, amazing attention to detail, beautiful setting and scenery. Nearly flawlass gameplay (minor camera issues). Balanced mix of small puzzles and fights. Lots of collectables. Big boss fights (especially Valkyries) are fantastic. Troll boss sadly used way too often.
Opinion on "Give me God of War" Difficulty:
Early game was the worst, but after a while it hardly gets harder. Rune attacks carry most of the time. Sadly it's mostly just buffed HP and damage, not really new mechanics and patterns. Some bossfights take ages because of the high HP stats. Took me about 130h. If you're not a complete sadist, you should just play on "Give me a Challange" instead.
