I read some really negative reviews for this place on Citysearch and one other review site. I just went there Saturday and I have to wonder if it was even the same place. Maybe it got new owners.
Regardless of the reason, I couldn't disagree more with those negative reviews. I went in February 2012 and I found one of the best if not the best game store I've ever visited. The staff was friendly but not pushy. The store was clean (shocking for a game store) and well-stocked. With two floors, there is plenty of space for miniature, board, and card games, and even a separate room for a role playing group.
I am almost exclusively a miniature game player, so I was ecstatic to find fantastic terrain and boards in good shape, as well as helpfully marked bins in which to put them. This keeps the store clutter free and keeps the terrain in better shape for longer.
The only negative about this place is that it's about 45 min to an hour from where I live, and I can't put that on them. I do regret naming names a bit, but Dream Wizards in Rockville - which is much closer to me - stinks on ice compared to Games and Stuff. G&S is the only store I'm going to patronize in Maryland.
