ahh.. finally i have another idea (just some idea) ;D -in D2TM, maybe add another sub-tech-tree system for feature, such as, Atreides can use El-Sayal(Coriolis Storm-Super weapon) by researched "Coriolis-Analysis" and "Weather-Control-Sattelite", and "Coriolis-Analysis" maybe effect to gained some abillities ex. storm-predict. ??? -Maybe kind of Teilaxu(spell wrong?) unit can revives corsps into a gholas or something? 8) -im said this idea in topic "water", but i will say it again, that water silo can be as a concrete-type structure? maybe uses other tilepic. in advance, tilepic can linking like a pipe in simcity, makes a big container of water image. and when WT is destroyed, gfx will show an area of underneath, and take it to calculates, ex. # grids that show water underneaths, more will make humidity-gauge(water gauge) low down faster. but maybe increasing abit of health to being-unit around that grids.(fresh and sweet air :D) -maybe skirmish mode will have bars for adjusting scale of terrains, ex. rock 3/10, spices 6/10, but conditions must not make bugs about tiles. :- -maybe add some another tiles like someone said(sorry that i cant remember you), ex. grass or oasis or something. but they must linking with a timeline. that's means grass will never found in early times, and when dune've grass. less humidity-requirement to units... -i dont sure what type of power that uses to motivate machines and vihicles in dune. but if i must dividing it, *the guild use melange for motivate their ships, so the guild maybe a tribe that's support-style(low-cost starport order fee), and cause of that... it will be most friendly with the highest melange player. *atreides is fremens' friend, in timeline.. early is atreides army, middle is fremen army(use tech-tree of fremen, but add some tech in every mission.), and last will be an atreides army with full powers of fremen-tech-tree. i think i will rest for a while, and i have thesis to do..so i will back to look after El-Sayal....
