Submarine Titans is a classic RTS. It is different than traditional RTS in the fact that your units are able to sit at one of five elevation levels and you are population capped by your own resources. I picked this game up for $5 in 2001 and fell instantly in love. The visuals are really nice (for the time), the music is rocking, and it always feels great blowing up submarines. The game comes with 3 factions, the White Sharks, Black Octopi, and the Silicons. There are no good guys per se in the story so playing as any faction is a treat. The White Sharks and Black Octopi are rival factions that hate each other. The White Sharks have very traditional subs, lots of armor, lots of torpedoes. The Black Octopi went for the sci-fi route and equiped laser on most everything. The Silicons are an alien species that happen to crash on the planet during their interstellar travel. They wish to collect enough resources to get off our planet and go home. The game plays very similar to other RTS of the era except there are no hero classes and no population limit out of the box (you can cap it in skirmish). The game has 4 resources. Metal is used in almost every thing you do. Corium is an element brought by the aliens and allows for some of the more exotic units. Gold is used for research. Air is required for buildings. Managing these resources isn't extensive, however, unlike traditional RTS where your resources are deducted when you click build unit, Submarine Titans allows you to build anything regardless of available resources. That means you can quickly need more mats than you are bringing in and all your production will come to a hault. The Silicons use different resources and play unique compared to the human factions. They share the need for Corium, but also require Energy for research and Silicon for everything. Structure building is unique since they do not have a builder unit like the human factions. I ran out of space so get the game for a $1 and have a lot of fun
