Speedmonster, actually there is... not really a tech tree, but the help icon isn't as fancy as a tech tree, but you need to do some back track a little. i.e. if you want to do gas, you look at gas, then it says what it requires then you back track on oil, etc. just manual doing thats all
Another thing just pop up my crazy mind about Quality, hope you guys can enlighten me here.
i.e. Gas (which you need Oil to make) so if i sell gas, i research on Gas which is from Chemical RC. What happen if i research on Oil (from Well & Mine RC), does that effect the quality of Gas at the end? and if i have both, does it boost the overall quality? or if i have a high quality gas, does it automatically produce a high quality Oil (w/o research on it?)
Thanks again for all the help, you guys are great!
