Is there a good venue in Denver?
There used to be two, but of course I'm also five years gone, so whether either is still around is unknown to me.
One was Valhalla's Games, near Lakeside Mall. We used to run things there regularly, but for a while they went uber-GW and all but shunned anyone coming in to play something that wasn't Warhammer. Then, when GW opened their own store ten or so blocks south of the place (since gone), they found the rug pulled out from under them. No idea if they survived to rebuild their customer base, but it was a decent place to game anyway- funny note, the back area for gaming used to be a warehouse of some sort, and has a curved tin roof- so if it's raining (or god forbid, hail!), forget any form of audio communication. Once the rain hits, your game is ON HOLD. ;)
The other- and to be honest, my preferred store in the area- was Bonnie Brae Hobbies, which was near Hampden and Colorado Blvd., about a block north of Hampden. Again, I have no idea if this store is still there five years later. If it is though, it's a gem of a store. The gaming area looks small, at first, but if you ask them nicely they'll open up the basement for you to use- more space than you know what to do with for gaming. Perfect! Their Battletech selection is just awesome- books, but in particular their mini stock is a thing of beauty. Great store, hope they're prospering in a tough economy.
A few other stores around town- Colpar Hobbies, for example- may have books and minis, but I never found much going on in the way of playing at those stores due to lack of area for it.
