So far I like the one in posts #24 and #25 the best. But I am still looking forward to better work. I miss some of the drama and detail you can see in the old AoE covers. Can you use the main menu artwork, perhaps? Yes, no problem. Yes, I agree, it can be much improved. Try setting it in SMALL CAPS. Also please avoid stretching it vertically, it can make text extremely ugly. I always like indicating that 0 A.D. is cross-platform with logos of Windows, Tux and Apple. Another idea is to represent the Creative Commons by-sa license and the GPL (v. 2 and above; sadly only v3 has an official logo).
