I like Thief THIS much
EDIT: That leaves a lot of other FMs to savor. We have several 'Dark Project appetizers' where you get a taste of the various locales that Thief originally brought us. Those interested can check out Haplo's "Darkness Walk With Us!", FrenchDecay, marbleman and JarlFrank's "In & Out" and "Tomb of St. Tennor" by vegetables (yes, Thief has vegan options ). All three of them have the primary focus on the Undead, though.
I wouldn't say ours has its primary focus on the undead, considering how varied the locales you visit are.
