It's been suggested before, and someone asked on the torque forums what it would take. He said that most of the game would have to be recoded, but the add-ons should be mostly fine.
ok that does not sound good for an update that could bring blockland into 201?
What? Badspot is very likely not going to do this, it would require a LOT of the game to be rewritten.
Reality check: I worked for garage games for a year. Kompressor was the Torque technologies director for like 5 years. We both think "upgrading" to Torque3D is a bad idea.
