The official Sierra game servers were shut down on 1st November 2008.
All US copies of Sanity: Aiken's Artifact came with a 23" X 17" poster featuring the box cover art on the front and a guide to the 80 psionic power cards on the back. Those who bought the game at Best Buy got an added bonus, a CD Single of the song "Sanity" performed by Ice T's metal band "Body Count".
As they usually do, Monolith has included references to their previous games in Sanity. There's a creepy portrait of Caleb from blood inside Krebspawn's Manor in Chapter 4, and while browsing an antique store in Chapter 2 Cain will come across a mint copy of Monolith's "Claw". Cain will even joke with the owner about how badly "Claw" bombed.
Users of Nvidia graphics cards will find themselves unable to load this game, as it always locks up at the level-loading screen while "processing world geometry". A fix for this problem does exist, just enable the Nvidia logo to display during gameplay in the Display Settings of your control panel (found in the advanced properties, additional properties of your 3d graphics card). It's anybody's guess why this should work, but it does.
This unorthodox but functional solution can be attributed to "winterfat" on the Monolith technical difficulties board.
Despite the numerous hang-ups, crashes, and freezes users have reported, Monolith has stated it has no intention of releasing a patch for this game, suggesting that the majority of problems are the fault of graphics card incompatibilities rather than actual gameplay issues.
This, coupled with an unsuccessful marketing campaign, is probably one of the larger contributing factors which has led to new retail copies of this game being sold for $2.99 at game outlets such as EB and Software Etc.
