Fenixp: Actually I can honestly say that I enjoyed Blackwood series more than most Lucas Arts / Sierra adventure games just because they were dialogue-heavy and didn't need too much backtracking to finish, not to mention getting completely stuck on a forgotten item.
Yeah, that was part of my lost post; basically it comes down to your preferences, as in most cases. If you prefer adventures with epic length and complexity or humourous stories or tricky (inventory) puzzles and lots of funny commentaries on your failed attempts at solving them, there are better alternatives. But if you prefer short dialogue-oriented interactive stories and don't want obscure puzzles to get in their way, the Blackwell series is highly recommended. The gameplay mostly consists of questioning people, combining the dots and talking to them again, which might not be the most original and attractive, but IMO it works quite well in the context of these games, I didn't mind at all.
And as a sidenote, when I think about it, to me playing "Ben There, Dan That" and "Time Gentlemen Please!" this year came quite close to the LucasArts experience from back in the days, in terms of humour, originality and gameplay.
StingingVelvet: Lucasarts games never screwed you like that.
The first ones did, too (e.g. MM, Zak McKracken), but we recently had this discussion in another thread already.
(Then again, they were still called Lucasgames back then, not LucasArts, so literally I think you are correct. :) )
