hmmh, well, i'm not realy sure, what i should make out of this :P
on one hand ... transportation possibilitys like trains, ships, ballons, planes are always a nice to have ...
this specific one looks ... well ... too old / antique
and while the interior could (probably) be easily modernized by mix-matching it with your scienc, scifi and steampunk sets ...
i can't say the same for the exterior ...
so my question: do you have (or are there any intentions to make)
- a more modern/futuristic looking train (something, that would go well with the alien/science/cyber sets)
- maybe even some kind of "armored" / (steampunk)military styled train
[also, ruined versions are always a welcome addition x3]
- animated "empty" waggons [so basically like mobile platforms to put your own stuff ... like cars, tanks, armors, canons, big attelery (on trains ftw xD), slave cages or ... whatever xD onto]
... maybe even something floating (like a magnetic levitation train) or maybe something more organically looking [like more on the darker / magical side ... that doesn't move with science xD]
... well tl:dr ...
exteriors for different time periods
... also as a side question at the end:
does this (or your overworld packs) have some kind of tiny worldmap train/road tiles included?
