4. Supreme Commander (2007)

The biggest RTS of its time is still huge today

Developer: Gas Powered Games

Genre: Real-time strategy

Your own giant killbot that doubles as a construction vehicle

Take part in the Infinite War, a massive conflict between the United Earth Federation, the Cybran Nation (appropriately named cyborgs) and the Aeon Illuminate (alien technology worshippers).

Like in its ideological predecessor, Total Annihilation, Supreme Commander places you into a mighty command unit, here called the Armored Command Unit (or ACU). Your ACU is the backbone of your base, economy and army. The structures it build are used to create more units, that you expectedly march across the massive map in order to exterminate your enemy.

What Supreme Commander does best is making you feel like you’re leading an actual army. The amount of units you can control within a single mission is beyond huge, and your ability to zoom out as far as you want (you can even see the entire map on your screen) creates a sense of scale that few other titles can even hope to match.
