Guild Wars 2

This general concept has come up before, but I think the room from the Taimi’s Game story step would make a perfect addition for guild halls – a place for guilds to have fun, test builds/group comps/etc.

You mean that small room? How is it better than the guild arena? You can test builds/group compete, have fun in there.

They should use the simulator as a training area, where you can spawn whatever enemies you want. It shouldn’t be limited to the guild hall though.

Obviously Taimi’s Game is just a precursor to opening up SAB as a guild addon
