Agreed, this seems more approachable, mainly because it is a layout challenge (which is a large part of the fun in Factorio).
The inaccessibility of fission is that it requires understanding the fluid system idiosyncracies. Maybe that will be easier after the changes to that system that will happen with 2.0.
Kind of agree. I wish combat robots were placed in the suit inventory and then came out as needed. It never felt right for them to be automated grenades.
