sony gave them a market with ps3, and there mistakes took a long time to correct, unlike xbone, which fixed them right away.
Yer but lets be honest the MS mistakes were bigger. It turned me of XBOX ONE and I will never get one.
DRM (even though they pulled it)
Killer Instinct released as episodes insead of a full game to milk money.
Halo collection was missing data on the physical release that needed a 20gb download to complete.
thats just three early examples.
PS3 the only real mistake was the high price. It wasn't every general public friendly.
to be fair, Xbox had a much stronger online service as well last gen, especially in the first few years.
Xbox had actually tried to get some Japanese exclusives (which made me go and buy a 360 at the time)
in the first few years of the PS3 there were very few top tier exclusives worth owning
sixaxis... no more words needed, right?
exotic architecture making the multiplatform games a lot harder to optimize than on the 360...
I could go on, but I guess I made my point already.
