Mhh, that are good points. Indeed it would make sense if he offered and wanted to make sure it's bought by Disney.
But as for games.. Disney doesn't exactly have any "able" development houses. Only thing I can think of with Disney and gaming is "super crappy movie tie ins" .. but hey, you never know what the times bring, maybe Disney buys EA..... ? Maybe they produce a dozen super AAA hit games the coming decade.. or maybe not.
But to me, imminent impact is Episode 7 and honestly.. if Lucas isn't directing it, I am already willing to give it a chance just by that merit alone...
And he was a shrewd business men so maybe this is the best thing that could ever happen to the whole ILM/Lucasarts/Star-Wars stuff.
