It's a goofy mix that will surely turn off more players than it turns on, but I find the combination a compelling one. Just the simple fact that I've never played anything quite like Warship Gunner makes my jaded self happy.
A good game for those that like to be in on the ground floor. It's unique in that you can build your own playable shooter, so to speak, but the gameplay is just average. Still, the combination of creation and shooter may be irresistible to some.
