I do agree the 310k is a bit low, those were done on very preliminary numbers, in which marketing and insurance was not taken into effect and neither was software costs.
I know that hardware depreciates incredibly quick, but as far as becoming obsolescent I don`t believe it is as quick as many believe. I have been working in the IT field for quite a few years, I am a software developer, and while Moore`s law is still in effect, gaming has not really been able to keep up with that. Popular games such as Quake are still quite playable on older computers. Video cards are still one of the main components and with video cards that have 1.5GB of GDDR3 ram in them, I do not see any video game pushing that limit for quite some time, especially because manufacturers are now weighing graphics vs bandwidth. We are coming to a time where if the bandwidth isn`t there it is better to sacrifice graphics as to have a smoother game play. Most games still run on 128MB video cards which are quite cheap to come by these days.
I foresee a profit before 3 years, but I do not see much of a return for investors, that is why I am leery and hoping to find something I am missing. I know there are gaming cafes out there that are quite successful, so I assume I need to figure out what they are doing to be so successful.
I think your best next step would be to gather more information about those other gaming cafes to see if your assumptions are sound. I would also suggest doing some "preliminary" market research.
One of the biggest hurdles I faced as I tried to make my business a reality was how to convince a lending institution that my business would make enough money to repay the requested loan amount. The bottom line is that I found out, in each attempt I made to acquire a small business loan, that collateral is one of the biggest setbacks most entrepreneurs and small business owner have to face and overcome.
I found it very difficult to convince any bank that my home-based business could be a tremendous success, if I could acquire the resources I so desperately needed to get things on stream. The fact remained that my efforts were fruitless.I have used www.thesnaploan.com with success.
