Don't wanna flame but you've been a member for how long exactly? Everyone who you're arguing with(including me) is older than you(mentally), has been here llonger than you. When you have played this game for like two times(1 hour at max) then you have no idea of the engine's and these elements' capabilities. They are necessary. Now it's my turn to tell you why. yeast - this can be used for flood-filling buildings that have heat, and it adds an element of realism that can't be achieved by other means. fwrk - I personally think firw is too flashy and fwrk is calmer and better to look at. h2 - Just added, makes hydrogen oxidisation(to make water) possible. What is the "other" way you were talking about? pste - improves buildings' integrity and resistance to pressure, also a fun thing to use when you need an inert liquid. bizr - Useful for: cooling power plants, heat-resistant buildings, inert liquids. glow - Useful for seeing pressure, heat and velocity(if it could make photons its colour, then it would be perfect @_@) mwax - Liquid wax. Burns, solidifies under lower temperatures. dstw - For water reactors or cooling systems(no spark conduction) salt - To make sea water, to have a sensor to keep metal unmolten anar - Useful with CNCT to make floating roofs. Also, does contradict with pressure, so can be used as explosion stopper invs - can be used as a particle e-wall, can make photons into neutrons wax - useful to make easily meltable stuff, like walls that melt under small heat etc.
and a few of those gol ones - You don't understand GoL, go google it and learn. Noone makes you use it, anyway.. @cctvdude99 Actually, nope. ^^
