Just for background info: Currently, I do not have a storefront business, but I did flip store locations across the country for 13 years for a franchise, meaning I took underperforming stores, set up all the systems, and made them profitable to then sell them to a new owner.

Thinking in my previous storefront experience mindset, my questions would be:

1) Would my franchise agreement allow it?

2) Would the shopping center lease allow it?

3) What is the age range of the gamers? (to see if they would be potential clients)

4) What are the interests and hobbies of the gamers? (to see if they would be interested in my products/services?

5) How much time will it require from me as the owner or my employees?

6) Will it be a distraction to me or my employees during working hours?

7) What would the gamers' expectations be when they visit my storefront?

Also, as a local storefront owner, "worldwide" exposure does nothing for my store's profits.  We relied solely on local clientele. 

Obviously, I do not need the answers to these questions, but I am posting them for you to ponder.  PS. I didn't see your previous post.
