As aforementioned by Sacred and Reventon, we’ve had plenty of tournaments and mini-events. Including playdays which handed out tons of XCash. This produced short term activity but never lasted long. Also, the hassle of organising such events was too much, as some people would rather play wanted games and others just wouldn’t show up.
All in all, they were good fun and introduced a competitive aspect to the game. Unfortunately though, it was all short-lived. Just about sums up BBH, to be honest.
Only long term solution left remaining is removing inactives/soft-reset. Even updates at this stage wouldn’t be enough to bring stable activity back.
