Guild banks are one of the banner features of patch 2.3, along with leveling improvements and of course Zul'Aman. We all know that you can store lots of things in them, although it might cost you. People are even making single-person guilds just to get to use the guild bank for storage. Come to think of it, why can't we have account banks, where we could transfer items and gold among our alts on the same server without having to use the mail? But that's not the point of this post.
No, the point of this post is a new use of the guild bank that has nothing to do with storage: checkers! Affix, from Tichondrius-A, has discovered that the bank is good for fun as well as utility. One player is using Netherweave, the other is using Arcane Dust, and they both seem to be having a good time (check the thread for more pictures). I have to say, this is the first time I've seen somebody playing a minigame inside WoW without AddOns or anything. Drysc speculates that chess would be somewhat viable, despite the fact that there is one row too few, what with the variety of item icons that exist. Tic-tac-toe should obviously work as well, though that's a fairly trivial game to not lose. Who wants to play guild bank connect four? Can you think of any other games that could be played within the default interface?
