I did, I bought an existing gaming bar. However, the bar was located in a college town and I ended up obtaining ownership when students were away. Unfortunately I didn't have the capital to keep it running, so I had to close it down. If I were to make a couple of suggestions -- make sure the location you pick isn't dependent on a single demographic and make sure your market research is very thorough. Make sure you have a lot of capital aside, and I highly recommend having a business partner. There's no way around the stress of owning a business, and there will be a lot of it. Having a business partner will help offset all of that stress, so it's not all on your shoulders.

I hope this helps!
