Thoughts for down the road

[Malufa]

I was thinking maybe after I finish Elemental Defense I might turn it into a "wars"\versus mode. Also I was thinking I might make an elemental Assualt wherein the Elements attack and your towers are the pollution things from the existing map. Another idea was to split the pollutants into 6 catagories of 5 each and make a versus map with a new lay out. Ideas? Comments? Concerns?
