Back when it first came out I picked up Zombies! It still stands as the second worst game I've ever played. Some time went by and TC released this little pseudo-rpg called When Darkness Falls. I picked it up to find I bought a terrible mess of a system. Needless to say, I've steered clear of TC since.
It's unfortunate as they out out games with themes I'm very interested in playing with. Their new one, Bump in the Night, looks promising, but I'm very skeptical.
Does TC have their act together now (probably not, if they're still crapping out Zombies! expansions) or are FFP going to steal their thunder and take over the horror boardgame niche?
The last two games that I got from Twilight Creations were both okay games. See my review for Humans!!! in this forum, and I think that my review of Innnsmouth Escape is still somewhere on this site, too. There is a real learning curve to game design, and both Twilight Creations and Flying Frog Productions have a ways to go before they catch up with Fantasy Flight Games... if ever.
