I am sure I have missed many games and uses for the Commander . Also, with titles such as Neverwinter Nights, Dungeon Siege, Homeworld 2, Startopia, Mechcommander 2, Empire Earth, Stronghold, Myth III, Warcraft III and Simsville on the horizon, I foresee myself getting a lot more use out of the Commander . The final philosophy for the Strategic Commander seems almost too easy. This is one product that you truly will get as much out of it, as you put in. If you are a serious RTS gamer and decide to put a lot of effort into mapping key combos, etc., you will be rewarded with improved gameplay.
Same thing goes for other titles as well.
The more effort I personally put into rearranging keys and tweaking combos, the more I liked the behavior of the device in my games. Also, practice with it made me more comfortable controlling it and using it quickly. As for whether or not you should get one, that is up to you. The only downfall I see is the steep price. This is sometimes too much for casual gamers.
