My spouse and I were looking for a specific Pathfinder book and didn't feel like ordering it online. A couple people had recommended Action Comics as a good RPG/boardgame store and we were in the area, so we decided to check it out.
The store itself is larger than many other comic stores. Most of the middle of the store is dedicated to tables. When we walked in on a Saturday there were four or five games going on. It looks like a popular place to play Magic or Warhammer.
The selection of boardgames was good, and I appreciated the "Free Boardgames to play" section, although I didn't take them up on that. I was also ecstatic that they had miniatures for Pathfinder and many other games. I don't play Warhammer, but they had a decent section of the wall dedicated to pieces from that game.
I didn't purchase any comics, but they seemed to have a good assortment. They also had other bits of nerdery: t-shirts, posters, statues, pins, materials for painting figures and dice. We ended up buying a lot of paint and brushes for painting our miniatures, and the employees/other patrons were very helpful with their advice.
If I lived in the area I would definitely consider playing there.
