Just to add to this proposed idea, it’s not in a shopping centre (looks at Andrea), this is a event social event and there will be alcohol for sale. :-)
As well as indie games, there will be interactive pervasive games that night along with games music, and yes, if you cosplay, come along. There will be a discount for cosplayers.
It’s a proper gamer geek night out.
So if you are interested in doing something at this Games Bar, do contact me.
