Well, mines a fair mix of influences, I guess. The flavour is not really classical fantasy, as there are too many 'realistic' and cynical politics going on for that. It also has a somewhat steamptech feeling due to the fact that I've incorporated that into it, (though the players have yet to encounter that much of it) and also something of a steampunk feel in bits; I'm heavily influenced by China Mievilles Perdido Street Station and The Scar, for instance IMC there are Manipulators - biothamaturges who engage in 'fleshtwisting' to make hybrids, better slaves, etc. Not exactly the same as PSS, but the influence is certainly there. Theres also a sinister undertone to the campaign, something I drew a lot from myself

but also from Lovecraft as the main horror writer who I have actually read anything by; the mysteries of the shadow-creatures, adn the sheer insane incomprehensibility of the once Elder Gods who still retain a fraction of their former poer and plot and gibber and spawn in dark corners of existence.
Tolkien influences? Not really that much. I mean, of course, this is fantasy, even if I'm deliberately trying not to be influenced by Tolkein, to do something completely different, I am by definition therefore being influenced by him

I dunno though, I just don't like his stuff that much, and haven't drawn much from it other than certain basic fantasy concepts.
Planescape, as my most beloved non-homebrew setting, has its influences, and I intend for at least a few trips to the planes and plenty of outer-planar influences. I'd say I'm also influenced by the crpg Planescape: Torment, an awesome game if ever there was one.
