I really enoyed Esoterrorists 2nd Edition, and I wish it would have caught on. Similar to another game I ran for a while, Conspiracy X 2.0, it really fills that awesom niche of X-Files type stories, and ventures further into horror elements. The reason I'm not running it today has nothing to do with the book itself. The reason I wasn't able to run the game is that I couldn't ever find anyone to play, and there wasn't any integration with Fantasy Grounds or Roll20. I advertised all over the place; roll20, Reddit, Facebook, but it just seemed to be a completely dead community. Several years ago when I read this, I think where someone might have succeeded in running it would be with an existing gaming group willing to try something new, but that resource was not at my disposal. Today, I think anyone looking for this type of gaming would probably auto-select the current version of Delta Green.
