I just discovered Race Track Builder on Steam, I like to know if it is really good! because it interested me Asseto Corsa!
I personally don't have it, but @Pixelchaser seems to be already a fan . So it must be good ! Does it worth the price ? Well, maybe not literally at the moment, but will definitely improve in the future so might buy it as well. PS: oh, here's the thread about it
its has similar workflow to BTB. however, the cross sections of a track are seriously more power full. and combining tracks intersections are possible. so its going to be much much better than BTB for complicated track designs. of which all real tracks are complicated.
