Pretty Awesome
I found it pretty easy to get into this game, with the help of a calculator you can actually plan out your trips and the amount of supplies you will need.
The progression was a little slow, considering the game is browser based. But it was cool once I could afford a hummer and enough fuel to cruise around the map. The combat is a bit sluggish in large battles, but that is unavoidable.
I would love to see the ideas in this game pushed further. If the graphics and story were beefed up a little bit I would have no problem paying for a game like this.
