I love the concept of this site. I had a similar idea a few years back (though my idea focused solely on a marketplace for AGS made games). I still intend to do it someday... but no immediate plans.
Anyway...
While I think the concept/idea has merit there is one major issue I see standing in the way. I am not trying to be rude, but constructive (I've been told I come across as arrogant when I offer this kind of advice so be forewarned).
The site design is completely non-functional. It's VERY unclear how to use/navigate the site (I don't even see a navigation). There are some icons that
appear to be navigation but they don't actually do anything and are located in a 'cold' spot of the layout. The layout is confusing and, over-all, you're unsure where to start or even what to do. This will put a LOT of visitors off. With something like this (where you want people to spend their money) one of the most important things is an easy to use website that is inviting and intuitive.
I would recommend taking a look at
Twitter's Bootstrap front-end framework or even some of the pre-made templates that are available from
WrapBootstrap if you want to keep it "in house" or, if there is money available, hire a professional designer to do the site design. If you are serious about making a go with this project, which it seems you are, don't cut corners on the site design. I've seen it so many times (near 20 years working in web development) where this kind of thing happens and a project fails almost before it begins!
I hope you find this helpful rather than arrogant. I really like the idea and would love to see it become successful (anything that screws major greedy corporations makes me happy). Good luck!
