Thank you for the suggestions! Naval Action seems multiplayer, is there a single player recommendation?
At the moment I dont think you can find a single player naval combat oriented game, but the overall pirate/adventure games, with simple/arcade naval mechanics
what I play nowadays is New Horizons:
Mod Release - Build 14 Beta [Last Update:28th October 2021]
Altough Its an adventure game I mostly just play the naval side, it has a realistic mode that imo makes for the best sailing feeling among all the other Coas/sea dogs etc. Is also being ported to a new engine (maelstrom), so you can check that out if you like the regular one
WIP - Porting New Horizons to Maelstrom Engine
Other than that, there is:
Buccaneers! on Steam
that if im not mistaken, comes out (hopefuly) in february (I think a public demo releases before) game looks really nice, and if you dont mind the lowpoly graphics, the gameplay (all that matters imo) looks the best on any SP sailing game yet, or at least fresh air to the SP genre.
New legendary sea dogs TEHO coming out soon I think, but naval combat is if anything more simplistic than NH, or just as NH in arcade mode so, if you dont like that first, this one dosnt look for you either
I think all other games coming are multiplayer
latest SP game with naval combat involved I remember seeing is Ultimate Admiral Age of Sail
Save 25% on Ultimate Admiral: Age of Sail on Steam
But is strategy and I havent played it yet, so I cant talk about that one
