Haha I can imagine how that went down
Sega1: Aliens.. Hmm, what the Hell are we supposed to do with this that hasn't been done before?
Sega2: Let's just pawn it off to someone else, we really need to make a decent Sonic game! The fans are pissed man!
Meanwhile at Obsidian headquarters:
Urquhart: Aliens?! Oh fuck, Bioware have never done this before! What chance do we have?!
Monahan: Just relax! Let me do the talking! I'll run this by the 3 Chris's.
After Obsidian completes the first look on the new "Aliens" game:
Bioware: What?! You just took Mass Effect and "rethemed" it in an Alien-esque style!
Obsidian: Sorry officer, we didn't know we couldn't do that.
Gearbox: Can we at least do a mission pack for it anyway? Or how about you guys make it for the consoles then we'll port it to PC!
