I remember the old days of BL - when there were massive battles in the slopes (whose host's name I forget), TDM maps that had effort put into them, and simple but fun and classic red vs blue IN A DAMN TOWN.
It's like the difference between Quake and Call of Duty - Rocketjumping around, shooting demons compared to a "realistic" intense ground-based gameplay, which is by no means interesting whatsoever. But - Call of Duty is popular, so EVERYONE ELSE MIMICS IT. Only a select few try their own stuff.
