Last Call Poker is an alternate reality game built around the frame of a dodgy poker site. The site asks for your "date of death" when you register. After filling out a profile and playing poker for a few minutes, you start getting phone calls, emails and had strange images show up on you screen. There seems to be quite a bit of story hidden within the site including movies (with ex-child star Todd Bridges–better known as Willis from 'Diff'rent Strokes'), audio segments, and live poker games played at cemeteries around the country (using the tombstones as cards)."
