TS, beside the high cost of starting business
another major concern will be the licenses for such business

If I'm not mistaken, currently there's no license for such console gaming business, better check with your local bandaraya office before proceeding with the plan.

and again, if I remember correctly, there's already a few cases of bandaraya raiding on those small shops running similar business like yours, but all they have is just a few tiny tvs and ps2 and loads of pirated games. I remember those shops are quiet popular with those ahbengs playing soccer games and school kids in their uniforms.

No matter how much money you got to burn, as long as you don't have a proper license to run the business, it's doomed.
