1) NO more Titanium submarines.
Visible damage to sub exterior! if I ram or get rammed, I would like the sub to visibly reflect this with totally smashed up bow. Some dents and textured holes would be nice when attacked by shells and DC.
2) More cinematic chaos in the control room during a DC attack, its way to calm in SH3.
3) Better animated watch crew, they should hold on tight in rough seas instead of having their feet welded to the deck, they should take cover from attacks, duck from bow spray and smoke ciggarettes
4) Ships with lights, flares and much larger smoke stacks please!
we should se smoke before we see the ship on the horizon.
5) Aircraft need to be much better looking, but from what ive seen of the trailer I think the devs got this one covered.
6) Better fog and rain would be nice too, both need to be more dense, fog should be complex fog (using particals like clouds.)
7) The Sub should ride the waves reather than travel through them like SH3... if this effect is at all possibe - that is.
8) Much more floating/ burning debris on the surface after a ship has sunk, I mean like 10 time more than SH3, but maybe with an option to disable it for lower end PCs.
9) Better ports and and coast lines, some rock formations are much needed!
10) No more death screen, we want to see our sub explode/implode/sink/ break up in to peices.
11) EASTER ISLAND!!!!
Thats about it
