Well, it isn't as high grade as some of the excellent adventure games you mention, but if you're really hungry for an adventure fix you could try the free games at: They offer free, user made adventure games using the AGS system, which was used to make most of the great Sierra games of the early '90s and late '80s. I myself have played many of the games and find them great fun. You should note that each game has a rating, based upon violence content, sexual content, and profanity content, and that extreme games have warnings on them. These games are not like the games you mentioned, but are actually old-school style point-and-click adventures. You might hate them. Also, most of the graphics are sprite based and simple looking, which may turn you off from them. I personally say give them a try, especially the game Apprentice, it's one of the best on the site. Good luck and I hope this helps!
