God of War sold 3.1 million units. This is an amazing feat for the series. Tons of people are getting into the series because of the amazing reviews that God of War has got. Not known to them is that God of War has always had this kind of critical acclaim. God of War has 94, 93 and 92 average scores for the trilogy.
God of War as a series has an understandable but wrong reputation of button masher and QTE fest. Its not that the games can't be played as button mashers on easy and normal difficulty and that there aren't tons of QTE's but they are blown out of proportion. High difficulties that players love to have these days never were button mashers and you have to be tactile and skilled to beat the game. The QTE's are highly cinematic and epic moments in bosses and against normal enemies they can be ignored and I'd say the games are fun to play when you don't do QTE's on every enemy when you've reduced their health.
The story and lore in old God of War games are underrated. Kratos might not be the deep character he is in God of War but the story has depth, there is no cussing and there are some very emotional moments in the games. Its amazing that they captured the essence of Greek mythology so well with the characters and setting. There are tons of players who never played the portable games and Kratos Collection would do well for them and they would see a different side of the old Kratos which makes him a multi dimensional character.
