Under SEGA we got Aliens:C.M, yet the unfinished RPG, Aliens:Crucible (Obsidian) was canned :-(
Apparently an Aliens RPG along the lines of KOTOR wasn't the type of Aliens game Sega wanted to release, but C.M was.
My very limited understanding of License Deals in the games industry, is that they are usually pretty specific.
Strict number of years to use the License , specific formats your game/s can appear on, specific regions etc etc(So when Activision annouced an AVP game for the home micro's back in the 8/16 bit home micro era, yet we never saw anything, my assumption was always that the license had been for specific time frame and specific hardware).
