I chose to roll on the flooding matrix, as it seemed most likely. There is a lot to like about this game, namely the easy way they handle differing gun calibers and armor. The torpedo hit table is also easy to use. And they certainly give you a large selection of fleets. Spanish, American, Russian, Japanese, British, and French are currently available, letting you fight pretty much any actual, or hypothetical battle you want.
Damage is handled well.
Fires can also be progressive, and may even blow your magazine. I usually don't like this type of progressive damage, preferring a simple approach, but this system makes it easy to use. As it is, it's very good.
