After a hard push the last couple of days I've got the game about 90% complete. Only a few additional things to add now and it will be complete. I've squeezed every last drop out of the optimisation for 8-16mb video cards and I think it I will work on them. I've lowered the texture quality and reduced the detail/draw distance as much as feasible. The goal was to run it on a 1999 power mac  G3. I don't care too much about jagged pixels. I'd rather bragging rights to be able to run it on prehistoric hardware.
