i need this fast internet for playing games
No you don't. You just need a fiber (or, heck, FastPath DSL) connection with good backbone connectivity, so latency is nice and low. I guarantee you that you can play your games on a 1 Mbps symmetric connection Now downloading the games...
its nice to see someone else who does buy this "you need the fastest internet to play the latest games" bullshit--Getting it Done.
The odds of any of the routing between you and the game server providing anything near 1 Gbps is astronomically low.
