Are expensive units useful for anything? It seems that spending three or four times more pays very little. Compare the last two infantry units, missile and rocket, for 50% more money you get a much slower unit with 2/3 life, and a meager 10% extra damage.
Compare heavy stug with heavy truck. For three times the price you get a little more life and half the speed!
Great game, but a bit too easy. I stopped at about 500.000 points and I never died.
I'd like the difficulty to start and grow without limit, until it killed me.
