I think that if you just (prepare the flame handicapant suit) combined roblox and blockland, then there wouldn't be anymore reasons for noobs yelling out opinions about one game that they don't even know is true. The features would mix pretty well. (I know this because I played roblox at one time) Then this could roll off.
Impossible, Roblox is browser based, Blockland is not and runs on torque, and, honestly, do you really want that builders club crap coming to Blockland and ruining the fun of the game? No one would want to play anymore if Roblox and Blockland were combined. At least, I wouldn't, because mixing them would turn both games into steaming piles of crap. No one playing Blockland= No money for Badspot. no money for Badspot= no more Blockland.
Oh yeah, and we would have literally tens of thousands of people from Roblox's horrible community coming here with there unoriginal names they think sound cool like "teh pwnzer" or "mr.1337lolz"
