Personally, I always liked arguements. It was a reason for me to force feed some clown a heapin' helpin' o'ban.
As for not being able to discuss some of the devs' older work... well, unless that other company said "no, you're not allowed, we'll sue" I don't see the problem. Suppose some one wants to ask MCA something about PS-T. Is MCA legally forbidden to comment, is he ashamed of the game or dis-interested? Beats me.
