Hoi as THIS is more about 'Rail Gun' technology, and its 'depictions' as 'Game-related' systems being currently promulgated, where applicable. Since you avoid the obvious 'perils' associated with 'Propellant/Charges' being destroyed/exploded from becoming "set off" somehow, then you are exclusively reliant upon NO 'powerplant/dynamo' interruption(s) causing any inability to respond with 'Firings'. Certainly, "back ups" are justified of being 'in place'/'accessible' then, so, those will no doubt require 'Safe Spaces' designated of such, with perhaps 'Snowflakes' "heat lowering"/cooling-down apparatus? I shouldn't imagine there being MUCH "overheating barrels/tubes" requiring thus, while it is usually anything 'motorized'/'engine-driven' supplying the weapon that is accessing it.
"E./G./R./etc." as 'moi' initially began 'Miniatures'-gaming through this/that/those with an Olympia-group circa 1994(?) and were continually adding upon these ever since, with "Scratch-built" versions equivalent-sort, or surpassing even, MUCH for what there was. By the time OURS became being in use, they were long-ago(years?) 'Discontinued' already, so, we decided to 'concoct'/design'/'refurbish' whatever could be made as them, as best we are capable with. For example, taking 'Tanks' out of the "Tank Battles" Game, I've designed PRE-"XXXX" Ultra-AFVs and they are V-E-R-Y 'Styled' as "Cyber-Net-Metric" assortment then. Taking their smaller vessels-hulls out of "Torpedo Run" still, I've 'fashioned' several ships into more contemporary/modern versions, accordingly of what such might entail or appear "as". Oh, then there were 'Toys' from "Dollar Stores"/etc. from which many 'Parts' had been pilfered and you should have seen the odd/bizarre/unrealistic semi-purported/semi-supposed "ships assortment" out of 'China'! WHOSE`S "Chinese`s" 'mindupset' are them?!? At least these furnished MUCH for "better uses" into yet plenty of games. ALSO: them "M~opoly" buildings I'd 'crafted'/'configured' are intended as being utilized for differing assortment now. More recently, the actual 'Buildings'/'Roadway'-features that "LIFE" contained will become of uses as well. There were several versions for that also, to where they then provide yet more kinds too.
