Correct me if I'm wrong, but wasn't the first proper high-profile retail game that PS+ offered since its inception was Tomb Raider Underworld back in December 2011, almost a year and a half after its July 2010 launch where a select few people who sort of "pre-ordered" it in advance got LittleBigPlanet as a freebie?
If so, then why people still complain about Games with Gold program which admittedly came out extremely late within 360's lifespan, but if you compare their initial year of offerings, GwG wouldn't actually fare worse than PS+?
I know that both comparisons are not exactly fair (comparing recent shape of PS+ to GwG now opposed to. comparing their first year of existence from the perspective of 2010 vs. 2013), though the latter still makes more sense than the former.
It can only get better. Quit yo bitchin'. I'm sure it will make its debut on Xbone later on this year.
And don't forget, you had to wait almost 1.5 years for the first proper retail game. But, on the other hand, it wouldn't surprise me if you said that people had to wait 3 years until Microsoft came up with GwG. And you wouldn't be wrong.
