How many years did it take you do make this? Did you do the music yourself as well? It's almost unbelievable this is the work of one person. Amazing... Well I have a challenge for you, remember Jumpgate evolution? The beta had like 500,000 signups. It was supposed to be eve online as a first person shooter. Make an MMORPG+FPS in space with good gameplay, and the graphics wouldn't have to be amazing even, just good gameplay, and you sir will be a wealthy man. Everyone wants an mmorpg+FPS set in space.
