While I was part of those forums, I noticed whenever I made a thread or a post, 50% of the time I would get negative responses. Negative Responses, insults, and the feeling of hatred spewed those forums. You would honestly have to watch what you say on those due to the fact that if you messed up, well, your going to get made fun of in an aggressive way
On the other hand we have Bethseda Forums. I noticed that Everybody(besides a select few : l) will show support and constructive criticism, and just a feeling of compassion.
FOR EXAMPLE: Just today I made a thread on here with a poll where I forgot a third option. The responses from the people that were part of the third option, were vary mature. They said "Since their is not a both option, I couldn't vote". You would think that would be a normal response right?
Well on the other forums, these are what the comments looked like. "This poll couldn't be more biased, awful", "Biased poll is biased" "Poll is [censored]". What enraged me was not what they were pointing out, I was furious about the fact that they cared more about the options that they completely ignored the topic itself
Well, all in all, I just noticed that this forum often shows the nicer side of people. Not saying that there aren't that select few that continuously act immature and not productive at all, but it's still the best out there.
Good job guys keep it up

This is also probably the best forum with decent mods that know how to act fairly when it comes to what people can and can not say. Some forum mods are well, a holes, like those over at Bioware. All I did when DA2 came out was maturely let others know my distain for the game and company and I was instantly banned. Then reading some other threads I found out the mods there lock and ban anyone who even say something against the Bioware company.
