In, I believe, December 2013 or March 2014 (I don't remember), I got Castle Panic--along with an another amazing game, Forbidden Island) as a gift from my mom. My girlfriend and I instantly fell in love with the game and have played it every few weeks since getting it. After months of playing, we bought the Wizard's Tower expansion, which added new elements to the game that made it a lot better. On April 1st, Fireside games (the publisher of the board game) released a small expansion called "The Dark Titan."
The expansion came in the mail on Thursday, but we were too tired to play it then, so we played the game last night, while learning how the new rules worked. We stopped after a while to go to sleep, but continued the game in the morning. There were a few bad calls on our part, and some bad dice rolling, along with luck hating us on card draws. The Dark Titan got summoned and we thought we were doomed, but in the end, we slayed all the monsters (orcs and other generic monster-types), and won the game, after which we felt completely joyful for overcoming those odds.
This expansion changes the game almost completely, and that's great since we started making our own rules to make it more difficult prior to this (like drawing 3 monsters at the end of our turn instead of 2). I would easily rate Castle Panic, along with all expansions, a 5-5. It's fun, easy to learn, up to 4-players, and has good elements of skill and luck (mostly luck). It never feels boring--it's the Orcs Must Die! of board games, and I love it.
