Game Servers?

Hello everyone. I have access to alot of server power and i'm not sure what to do with it all. I can host pretty much anything Websites, VPN, Proxies etc but i'd prefer to host game servers (that's more fun!).

Any game that supports linux would be fine such as : Cs1.6, CS:GO, Minecraft, TF2, CSS and a whole lots more.

Would there be any interest to rent Game Servers for a low slot cost? Obviously it would be alot cheaper than the official Game Server Providers.

I have access to multiple locations so that wouldn't be a problem either. Any opinions?
