I've been going to Gatehouse Games for the past 12 years, since it was in its original location in nearby altoona (very small store at that time). The store has grown over the years as the collective group of gamers grew rapidly. Within the first few years the store moved to the Hollidaysburg plaza in Duncansville, and has been their ever since.
Ever since I've started going to the store, I've had nothing but good experiences with the store and the owner, Tim. Tim has been more than willing to help me learn a game, teach me to paint and do model conversions, make gaming tables, or just do a good bit of leg work to find that hard to find item I'm looking for. He carries a huge variety of games, and is pretty knowledgable about most of them (including D&D/AD&D, Games Workshop Games, Magic, and many CCG's).
The store is awesome, as i believe there is over 2000 sq. feet of store. He has over 8 tabletop wargame tables (full terrain and looking awesome), and many many tables for cardgames and boardgame players. Not only that, but he has novels that are about the games he carries too (like D&D novels and Warhammer Novels). This place is a gamer's paradise.
When you come to Gatehouse games, you don't just buy something (unless thats all you're looking for). You leave with more than just product, you leave with an expanded knowledge about a game you're thinking about playing, and wisdom from a gaming veteran. And the best part is Tim isn't high and mighty about it, he speaks to you as an equal, and treats you with respect. New gamers and veterans are treated equally within his store.
Not only do you get all this, but you have central PA's largest gaming store carrying the most product you could want! If you're new to gaming, or even a veteran, stop on by. I'm sure you'll see Tim as he's there every day. It's definatley worth the travel for the experience. And sure sometimes things can be cheaper online (although gatehouse games sells things at manufacturer's suggested retail like stores are supposed to), but you should always buy from your local hobby store to support them. If you don't then someday you may not have a place like Gatehouse Games to play.
