What? Where do you come up with these conspiracy theories. SM is the far larger game with far more potential. SM has 20+ people on its staff. BD is 10+ years old and around as basically a legacy game. Still, BD earns enough income to support itself and its small staff of 1(+ admins which are paid with tokens spent on their worlds).
Please do not spread these idiotic false rumors.
Edit: Elcent informed me you may mean BD:EA instead of BD. 2 points, BD:EA has investors funding the game and secondly, SM was born from funds generated from Battledawn. So if TS does decide to spend some funds generated from SM in a new game, you shouldn't be complaining. It's basic business, you grow the company with either the funds you earn or by taking loans in the form of investments or credit lines.
The SM staff is quite large and TS continues to invest money right back into SM, so unless SM reaches the stage BD did where it essentially got ignored for years, the SM community should not worry.
