Developers wanted an EASY way to target a large audience. Ding ding SE account holders.
Developers want to make sure that many types of computers with different specs can run this game at the same time with equal in game response. Ding ding lets ask the SE accounts what kind of PC's they use.
PS3's are all the same exact specs. No point in testing out more than a few of those just yet. If we have one, we just duplicated the entire PS3 audience.
SE account holder. PC specs. Pick and chose, randomize the rest. Target audience achieved.
Seriously shame on anyone who QQ's because they have been playing since Jesus was alive and they are "loyal". They just want an audience to test based on specs and filling in the rest to create an audience. They dont care how long you've played. It's business. Get over it.
But one thing im suprised nobody has suggested is that they MIGHT have compared some SE id's to players who have a bad account history. It would be bad business to let in players that have multiple GM calls against them or are flagged for possible RMT.
