I assume this is a "spiritual successor" to Pacific General
This game really looks fabulous in many ways, but in some it doesn't so here's some (hopefully) constructive criticism of appearance:
1) It's commonly-known that the BEST way to identify ships (or specific ship classes) is by their side view
, silhouette profile as some have single or multiple funnels, command towers, other distinctive features, camouflage to foil subs, etc. which is why most encyclopedias and guides look like this:
Most ships look too much the same from the pure top view --carriers are rectangular, nearly everything else has the same pointed stern and prow across all countries. It's POV perspective of high altitude bombers only.
Perhaps more of a 3/4 view (like the land units) could serve as a compromise?
The Yamato BB in Pac.Gen., for example (Armory e-roster), is a muuuuuch more impressive-looking and distinctive ship icon at the bottom of the screenshot here.
These OoB: Pacific
ships kind of look dinky too compared to the land units. The look is inconsistent between the two.
2) The ocean (though it has a realistic texture of waves) appears greenish/brownish/grey? That looks yucky! The ocean is supposed to be blue
because water reflects a blue sky. And what happened to reefs and shallows? Besides visual appeal, they actually serve a purpose in restricting larger vessels (BB, CV, CA) from getting too near certain islands.
Perhaps old Pacific General was deemed too overly-colorful in comparison:
but the real world of the South Pacific is too:
Perhaps a tint of blue to deeper areas and some aqua shallows can be added? Just a suggestion. Nice work, otherwise!
