First off, there’s an active and large minority of non-European users on the forum. Second, the European Championships aren’t the most competitive continental championships across the board as @Vojthas pointed out.
I do believe that there’s more European users on the forum, but the bias towards European events is annoying. I know I’m not the only person that has complained about this issue in this thread. Like I said, I’m fine doing one European Championship a year, but it seems fair to do a Asian, African, or Pan American Championship as well. One could argue that European users have an unfair advantage in European Championship prediction contests, since they have more likely than not followed those championships much longer, and more closely, than non-European users.
Honestly, I just want a little more variety of these prediction contests. We seem to vote for and do the same events every year. It would be nice to throw in something like Floorball, Lacrosse, Women’s Baseball, Ultimate Frisbee, etc. every once in a while just to mix things up a little.
