LucasArts was part of the deal when Disney bought LucasFilm, and as you probably heard, they just closed down LucasArts.
LucasArts had in past years been practically just about Star Wars games, and Star Wars games will continue, as Disney intends to license Star Wars out to other developers. I enjoyed BioWare's Knights Of The Old Republic, and I haven't played the now-free MMO The Old Republic, but I heard it's all right.
What is stupid though is the cancellation of current projects, including what would have been the first M-rated Star Wars game, Star Wars 1313. While 1313 was hyped up, I wonder if it being too dark didn't mesh well with Disney's brand, or if it would have been cancelled anyway if this decision was inevitable. Seems like such a waste when games in progress are totally scrapped, but obviously Disney doesn't care. And they sure doesn't care about the 150 now-unemployed former LucasArts employees.
Though the good ones will end up elsewhere, I'm sure. When I think of LucasArts in the non-Star Wars context, I think of Sam & Max, Monkey Island (both of whom saw revivals from Telltale Games), Maniac Mansion, and the one-shot Grim Fandango...now those were good games, back in the day. And they are still good games now...I rarely replay games these days but I could easily see myself making time to replay LucasArts's best, even though I'd replayed many of them back when they were new(er)!
Thankfully there are companies like Telltale Games and Double Fine that carry on the talent (including the same people). I recently played all of The Cave which was certainly interesting, worth replaying to get all the endings, so games with some of LucasArts's genes can and do certainly exist.
It is kind of sad though, I remember starting up a game, and upon seeing the LucasArts logo, knowing I was in for a treat. (Same with the Rare/Rareware logo.) I guess times change, unfortunately. Even if Disney retains the LucasArts name or logo in some way, as I heard they might for licensing purposes, it will now be a reminder of the power of corporate Disney. I generally like Disney products and franchises, but I disagree with the axing of LucasArts. Boo, Disney.
