i think badspot said at one time about whatever discussion something like
"game engines are very spendy to buy the licensing. you get ahold of that 50-100k engine, then you are expected to make content at that quality" /misquote
torque is good enough for blockland. affordable and the features it needs.
i dunno what involvement BS currently has with garage games.
but this seemed like a 1man project for him. like a great foot in the door for careers ahead.
im sure he will be on other engines doing much bigger things someday.
