No, I think by the time Sierra decided to re-release SQ1, LSL1, QFG1, KQ1 and other _Q1 as _Q1 VGA, they were exactly the EA of Adventure Games.
LucasArts titles are spectacular - humor, writing, character, world, game design are all better by a long shot. I'm a Sierra fanboy, but Gilbert was one of the first one to point out how superficial was the challenge "not to die" in all the Quests. If you must play through something, give the first two Monkey Islands a shot, I urge you. Scott Murphy mentioned in his 2006 interview that during the production of SQ4, he played the shit out of that game. He found it to be utterly brilliant and absolutely gorgeous. He also said that "working at Sierra at that time was a very miserable experience."
Space Quest has been, is, and always will be on the very top of my Sierra favorites list. Those games are impossible to throw off from their position as being the first game I ever played (SQ1), the first game I ever played and beaten by myself (SQ3), the first game I bought on CD-ROM (SQ4)... you get the idea. Space Quest is to me what
ing Christmas is to some of you.
Not far from that list is the Leisure Suit Larry series, more topical now than ever, since it showed how to do sex as a theme in a video game without ever losing class, becoming pornography, or losing the sense of "adventure." LSL2 and 3 are among my all-time favorite "text parser" games of all time.
