I don't understand the aging up distribution of resources for the Celtic civilization. To reach age 2, you require two houses, or 150 wood, and 300 food, which is a little too much. For advancing to age three is an outrage. 500 food, 400 wood, and 500 gold. What do I look like, Bill Gates? Come on, make the resource count even for every civilization, because the units aren't the best anyways.
