It just depends on the edition IMHO - many of them aren't worth the money but some are pretty nice (according to one's tastes of course) - the Sam and Max editions, Brigandine, Dark Crystal Tactics, the Return of the Obra Din and (especially) Thimbleweed Park are some good examples of nice ones. Zombies Ate My Neighbors looks great too - although it hasn't shipped yet (it is finally lurking in their warehouse though).
