You may know me, you may not but lemme just tell you a small story.
I was the leader of the Halo: Retreat and Retaliation mod for DoW, we also had other sister project such as the HaloGen mod for CnC Generals. One day Microsoft sent the old "Cease and Desist" order to HaloGen after 3 years of hard work from that team, we all took inspiration from this mod, and they were just about to release when they recieved the order.
Now our mods we non-profit, fan-based mods which we tried to pay tribute to the Halo universe. Now before you guys say something like "ha ha, well you should have expected this" attempts were made by both teams to contact both Microsoft and Bungie. I personally made 3 attempts. We never recieved replys from either. So we decided to continue. Now after a few years our work is now wasted. I have even recently contacted MS's IP department and they gave me the worst and most stupid email reply ever. (If you wanna see it, visit our forum)
So basically i just wanted to give a warning, if Ensemble Studios is acting without either company backing them, then they will be screwed. If you havent got the backing then stop now. If you have then by all means continue.
