There once was a time, before closures, before Lucasarts, when the name "Sierra" meant premium PC adventure gaming. Those days are, sadly, long gone. But they will not be forgotten!
If you head over to Sarien, you can take part in a little project that's part-game, part-museum piece, with old Sierra adventure games running in Flash on your browser. The graphics are the same, and if you want, you can use text commands, but a right-click menu system has also been introduced to speed things up a bit.
That's the game part. The museum part comes in a gallery of assets from the old games, with a wide range of things like background art available for browsing.
Interestingly, it also supports...well, multiplayer, with the internet-based nature of the games allowing users to see other gamers attempting the same puzzles as you are in real-time.
Currently three games are supported - Leisure Suit Larry 1, Police Quest 1 and Space Quest 1 - with more promised.
