Well, I've finally reached that point where I have enough of my old west town and figures done that I can now branch out into some weirdness. The Valley of Gwangi was of course my primary inspiration for this game. I ran it at a mini-con that I run here in Chicago, and my players had no clue that dinosaurs were going to quickly become their primary targets.
Started off simply enough. 4 gangs, each gang had a civilian they had to escort off of the table. The town was very busy that day, with Doctor Hackenbush having rolled into town with crates of his patent elixir on the back of his wagon attracting a crowd of onlookers and rabble-rousers.
Soon, the stage came barreling into town, with the driver yelling at the top of his lungs "Run! Run!!!" The reason for this was soon evident, as man-sized lizards came tearing down the street after them. The lead one leaped over the coach and landed right on the back of one of the horses, ripping into it and causing the stage to careen out of control.
People and horses scatter in random directions as more beasts flood into the streets. The players try and round of their civilians and get them to safety with varying degrees of success. The Pinkertons duck into the bank with the manager to try and get him out the back of the bank. One of them made for the roof, hoping to be able to get better shots at the beasts, but he soon learned the flaw in that plan.
Then, when the players thought things couldn't get any worse...it did.
The game was a ton of fun. I made up the rules for the dinosaurs, and I wasn't sure if they were going to be completely overpowered, but I did want them to be really tough and scary for the players. They were able to take out about 3 of the raptors, and one of the pterosaurs, and in a hail of lead, the allosaur. I was revising the rules a bit on the fly, but it all worked out.
