One of the most stupid decisions I ever saw by a gaming company. Blizzard, Bethesda, CD Project Red, Ubisoft and many other maintain huge forums. There are clearly two reasons Bioware are closing their forums.
1. It's a business decision, forums don't generate money, they require money for a considerable web traffic, for maintaining and moderating them.
2. It removes a biggest channel of criticism, a deed worthy of the Chinese censors.
BSN was a valuable channel of feedback from fans to developers, I know there was sometimes unfair criticism but fans gave a lot of constructive criticism too. I got a link to a fan-made fix for a DA:O bug which was never fixed by devs.
BSN was a place for Bioware fans to discuss Bioware games and everything else and you could meet a ton of interesting people and have surprisingly deep discussions. Waiting an upcoming release with an intensifying hype and then after the release interacting with thousands of other excited fans was a great feeling. Even loving to hate DA2 and ME3 endings was fun! Destroying a community of your most dedicated hardcore fans is a terrible decision, Bioware.
Snowball's chance in hell I'll use my real name on Facebook discussing a game where my colleagues and tons of facebook lunatics can see it. Are you having a laugh? 140 characters limit on Twitter for talking about Baldur's Gate or Dragon Age or Mass Effect? Give me a break. Registering on reddit with it's cult of Trump supporters or going to interact with Tumblrinas? No thanks.
Last but not least ME3MP forum was amazing too. Huge community of reluctant at first but then die-hard fans, constant interaction with MP developers, making new friends. Pity you decided to kill it.
