Quote from BuddyCan you list some HL2 sp mods with cool concepts behind them? I wasn't looking into it very much last year, maybe missed something good.
There's mine, called "Radiator" (though maybe too esoteric for its own good) http://www.radiator.debacle.us -- I'm trying to make the "high concept" mod except without the ugliness that usually comes with experimentation, you can decide whether I'm successful or not, I guess
There's Dan Pinchbeck's stuff, Dear Esther and Korsakovia http://www.thechineseroom.co.uk/ (fairly ugly... the displacement work makes me cry... but pretty high concept and lovely voice acting)
I love anything by Brendon Chung (though not HL2, it easily could've been) http://blendogames.com/ (not ugly, but emphasis on simpler cleaner visuals than the noisy dirty stuff flooding the mod scene these days)
Nestlings (not ugly, but visually kinda mundane, nice and short) http://www.moddb.com/mods/nestlings
Flesh (neon lights, pretty ugly, too many colors -- but a cool mechanic where you see from the eyes of monsters) http://www.fleshmod.com/
