Sanity: Aiken's Artifact, the first game to ever have DLC

Here's an interesting one, the 2000 PC action-adventure game "Sanity: Aiken's Artifact"(which has Ice-T voicing the main character) is unique for being quite possibly the first game to ever have DLC, which came in the form of "talent cards", skills for the main character you could unlock in-game. There were ones you could only get via pre-order(and those became hard to get as EB Games ended up running short of them so some people that pre-ordered the game didn't get those and instead got a tie-in comic to the game which was originally meant to be a bonus for another retailer) not only that there were other exclusive talent cards that came on a demo-CD that was in included in the November 2000 issue of PC Gamer("The Next Gaming Gods")and the Realplayer website offered more exclusive talent packs if you paid them 15 dollars(then they would send you the talents via installer packs), there were also some more exclusives ones offered through developer Monolith Software's website at the time. This was all explained in an interesting Youtube video I came across, the guy in the video said he had all of those bonus talents on a floppy disk but wasn't able to find it and a recent comment he made three days ago on the video said he's not yet been able to find it. So i'm hoping we can get a search going and find those talent packs. So far only the PC Gamer one has been found (as someone uploaded the entire demo-CD online) I asked the guy that did the video if he could upload the bonus talents he got with the pre-order, so that leaves the one on Monolith's old website and the Realplayer ones.
