yeah what tulamide said. quazi made thumb war.
you can have complete control over the 3d position of every vertex in a distorted sprite(which is how thumb war works), or load 3d models(feature didn't exist when thumbwar was created)
the 3d position of vertexes thing allows for interesting stuff like thumbwar or newt's recent 3d rts example with random 3d terrain, but you really have to love math to pull it off. it doesn't do the work for you at all like most construct stuff does.
