Modern Maniac Mansion
Wired.com is reporting on a Modern remake of classic adventure game Maniac Mansion. From the article: "The new game is almost identical to the original, except for the graphics and sound. Like the original, it has seven characters you can assemble in groups of three to play the game, and the puzzle-filled adventure has eight different solutions, which vary based on which characters you choose."
Syberia sold enough to justify a sequel. Same goes for Tony Tough, Wanted and Runaway also a sequel to the Longest Journey is in the works. They are by no means megasellers, but it seems like they make their mones if you can limit production costs.
Yup, in a commercial sense, Adventure games are dead. In a freeware sense, however, it has never been easier to create your own adventure games. Sure, there may be another old-school, official Monkey Island, or King's Quest, but independent developers are churning out more high-quality AGS titles than ever, most of them completely free.
Check out www.gamehippo.com and www.the-underdogs.org (as mentioned before me) and download some of the excellent titles.
