Yeah.
What I've learned so far.
If you like torpedoes go the Japaneses DD line and maybe the Cruiser line as they have Torpedoes as well. And the Jap torps are better then the US, as they should be. If you like guns go US Cruisers and DD's. And for guns you can't seem to beat the St. Louis (Tier III). I went the wrong line as I was trying to mix it up with my son and take different things. Once you upgrade the Hull on the Louie it has 14 guns. 14!
My son now also has a Battleship and he's in love.
