If you join the ICO with $100, you can buy 100$ later on with just $16.
If I understand correctly, you get tokens called OBITS.WARRANT according to the amount with which you participate in the GetGame ICO. At some point, you can buy OBITS for $0.16 by using the OBITS.WARRANT's. OBITS trade currently at about $1.00.

The GetGame tokens are called REALITY, and can be freely traded on Bitshares.
