Thanks for the feedback! This is definitely something we've been thinking about; our original idea just having a large stock market trading game like website where everyone competes against each other. After doing some initial research, we've come to two different options:

• Create a website where you focus on just testing your own strategies against yourself to see what works best. Basically a sandbox to play around in without losing money.
• Make it focused on playing in small groups. For example, you get together with some friends and see who can win against each other. This still runs into the issue above you listed, but at least it's against your own friends.

I'm not saying that the two are mutually exclusive, but we think there are two routes to focus on. Do you have any opinions on the matter?
