Like most of the games on this list, Total Annihilation did something special compared to every other real-time strategy at the time. One of the most obvious would be the massive scale battles where you could have up to 5,000 units on the map at the same time. Another neat thing was how the resources where handled in this game. Instead of having harvesters going to work, Total Annihilation depends on structures which provide a steady stream of metal and energy. What makes this mechanic interesting and complex is the fact that different structures and building units will have different rates at which they consume both resources. Overall, what do I think about this game after all these years? While there is a definite nostalgia factor, I would have to recommend the much more modern Supreme Commander.
