From what I understand the gameplay is based on a preexisting ship v ship system, with some tweaks.
The ships, in resin, are pretty large for the type of game - and mantic resin stuff is usually very nice - so I’ve no problem with what has been shown so far.
The two dwarf ships are the smallest ones, those shown for orc & basilea the larger
Given my first comment, plus the fact that in game all the ships are on bases, you could probably fine stuff to kitbash/work as proxies.
It’s released in my birthday week so I’ve ordered it (plus I need a slight break before doing KoW army 9!)
