The guys working here are great. I went in recently and ended up talking with a sales guy about the new upcoming World of Warcraft release (Mists of Pandaria) and enjoyed a shared laugh about fans' disappointment over the proposed race and class divisions.
I'll try to side-step the geek talk, except to say that it IS possible for an Alliance and a Horde player to be friendly in real life, even if they've unknowingly caused each other to punch their monitors in the heat of battle.
The staff are very friendly and the store, though not big, crams in all the games you need. It's not an easy store to miss because of all the posters and ads everywhere - inside the store and out. If you want to pre-order a game from Indooroopilly EB, I've done this before (Rise of the Lich King - Warcraft) and had no problems whatsoever.
The store is usually very busy, and during holidays it's hard to move. In this case you need to use crafty, diagonal, nudging movements to get to the counter. Once you get there, though, your experience will be as you want it to be - quick if you're in a hurry, languid if you want to chat. The sales staff are very good at following the ebb-and-flow vibe of their customers.
If I had to work in the retail sector (I'm no salesperson), I'd work here. read more
