Enterprises

Adding an enterprise = 30gc/month? Is this a little pricey? That's $36 per year in gc or can you earn that back somehow?

You can win gold coin rewards for being a top enterprise. Also, you will need an enterprise to advance in game levels, which also awards gold coins.

Finally, if you are really strapped for gold, you can advance your countries war level by conquering computer controlled countries.

Ad to that that enterprises give you a lot of extra options in the long run and it is worth it. Just be ready for the long game. Enterprises are not worth it if you are going to be playing shorter then 6-9 months.
