Thousand Year Old Vampire is a new solo RPG that's up on Kickstarter now. Take over the role of the titular vampire from the very beginning with the loss of their humanity all the way until their end. It's great for those vampire afficionados (I'm looking at you, Suzy) and anyone who might not have an RPG group around and just want to embrace your darker side.
From the campaign:
In Thousand Year Old Vampire you chronicle the many centuries of a vampire’s existence, beginning with the loss of mortality and ending with inevitable destruction. Prompt-driven play and simple resource tracking provide easy rules for exploring your character’s human failings, villainous acts, and surprising victories. Expect gut-churning decisions and irreconcilable acts.
The game mechanics are simple and intuitive. Play progresses semi-randomly through a book of Prompts which let you explore your vampire’s wants and needs, resolve problems, and chart the decline into senescence. Play can happen entirely within the character sheet or can become a journaling activity--both work equally well.
Vampires, for the purposes of this game, can mean nearly anything that is functionally immortal, doesn't like daylight, and preys on humans for sustenance. I like Montague Summers-type vampires myself, but this system is designed to be flexible.
All you need is the book or PDF, a d10, and a d6. This is a solo game for you to play in lonely places wrapped in darkness, but can be played multiplayer if you like. Play can take from one to three hours, depending on how you go about things.
The campaign's more than 24x funded with 20 days still to go.
