I can't believe no one said this one yet. Rule the Waves. It is a Naval game about 1900 on. Its turnbased for its main gameplay (where you design, research, build, etc) and has "realtime" (stop, slow, and speed up options available) tactical battles. When designing ships, you chose the main armaments, secondary and tertiary weapons, engine power, armor levels, tonnage, torpedoes, etc etc.
