What you need is for XilliX to come and tell you what he thinks ;o)
IMPO: I have issues with the obvious technology used in the Winch, I would be happier for it to be simply a slave driven wheel with pulleys rather than all the steel plating and control panels we see in game currently. (No disrespect to the moddler).
As for Chemistry, I see Alchemy. This is the comparison to RL that I see as more appropriate. Science, as it is now, is just an observation of the natural world, and Engineering is the harnessing of what is learned from physical sciences.
I want to stress this is a purely personal opinion and is not sanctioned by settings or the PS staff as an entity.
(I don't like that as a guild name btw :oS)
