Unbelievable and underappreciated
For those who don't know much about this game, it's basically a vehicle shooter game combined with an RTS game. You drive around in difference hover tanks on different planets while from a first person perspective while commanding a base and army. The typical RTS elements of resource gathering and army/base building are extremely smooth and easy to perform, and the battles are fun and interesting.
Anyways amazing game. Keep in mind it IS old and therefore the graphics aren't the best, but if you are able to look past that, give it a try, you might be surprised.
