Requiem Vampire Knight is in their final week over on Kickstarter. They funded pretty quickly after launch, and have been chewing through stretch goals since then. They're getting closer to being 2x funded with their campaign, which would be pretty sweet. That would be pretty close to unlocking the Campaign pack, which would add solo and cooperative modes to the game. To make their way to it, they've put up some great add-ons to the campaign.
As for those aforementioned add-ons, you can get either a 2-player or 4-player game mat, special busts for each of the factions, card boxes and sleeves for the myriad cards that come in the game, and the 4-player expansion pack. If you're interested in those products, a lot of them are Kickstarter exclusives, so you've only got this last week to get in on the action.
