Calgary has Sentry Box, and therefore is fine in my books!
The Box is indeed the biggest games store in Canada, probably North America, and maybe even the world. Around 14,000 square feet of shopping, plus a mezzanine for gaming space. An old factory space. The city of Calgary once tried to buy Gord out for the C-train line that now runs across from it and he couldn’t find anything like the building at any price to replace it.
I’ve been going to the Box for probably 30 years!
