Bluddy: OK there's an attempt here to excuse Roberta for what KQ8 was. This is completely wrong. Roberta and Ken pushed for this direction. Adventure games in general were doing badly in the market, and 3d was clearly taking over. To them, this was how they would invigorate adventure games. This is entirely Roberta's design -- with the action and everything.
We have to remember that Roberta wasn't a great designer by any means. It's generally accepted that the best Sierra games were made by Jane Jensen, Christy Marx, and the Coles. The best-regarded King's Quest game was KQ6, designed by Jane Jensen. KQ7 wasn't really made by Roberta (if I remember correctly), but KQ8 was a result of Roberta getting intimately involved and trying to 'rescue the adventure genre'.
If you want to understand why Sierra made the games they did, focus on one fact -- Sierra's designers didn't play adventure games. I repeat -- they
didn't play adventure games. Ken Williams, the man responsible for steering Sierra's direction, didn't play an adventure game in his life except for SoftPorn. As far as we can tell, Roberta also didn't play any adventure games. Ken's excuse for this was that playing existing adventure games would taint their own games with other people's ideas.
IMO Sierra single-handedly both built up and destroyed the adventure game genre.
That's kind of a sad truth if that's the case. I had no idea the Williams' didn't play adventure games. Okay, I don't know what adventure games existed before "King's Quest 1," but there's so much they could've learned from other designers when they were doing their later games at least.
That said, Christy Marx? So, the Conquests games are generally accepted to be some of Sierra's best games? That is news to me. Personally, I think they're good games, but not Sierra's best.
