I posted this in another section but this seems like another good subforum to say this in: if you're really nerdy and like to min/max your balance sheet, research technologies, and invade neighbors with no warning try out Neveron. It's a super old game and its based off of battletech, but for somebody like me that never played battletech, its still a lot of fun. You have to play it in IE cause it was made in the late 90's. Go to the help tab and enter the IRC chat room if you have questions. Here's the link. Neveron
If you end up being given land next to another level 0, you can possibly invade them right away to see what battle is like. If you end up wanting to make another empire (you will) use "More Money" for the promo code and you'll get 10mil extra.
