Flawed very badly in favour of USA forces, after starting to win as Japan I found my ships could no longer detect USA subs even right over the top of them ?? aircraft combat is hopeless the Zero might as well be a ww1 triplane, map shows ships and planes , scramble forces and none there ?? then suddenlt there is an American supply fleet supplying targets.. in my opinion graphically great but biased and flawed .. Japan ships collide and damage each other, however American ships drive right through each other like ghosts .. game needs really sorting out AI wise
