A really hastily done map called "The Best Game Ever!" that was full of badly done sexual references, racism, and homophobia. Also, it had no goals, when you died you got teleported to an unreachable place in the map, and the terrain was shit. Then I *tried* to enter a DotA to see what all of the fuss was about... Instant kick/ban.
Not really a great way to be introduced to BNet. <.<
