Gaming generally requires low latency, not high bandwidth. Does this do anything for latency? (I'd have to think that FO is probably better than copper wire, et. al., but I'm not 100% certain on the physics.)
My counter-strike source latency on a server that was maybe 20-30 ms on DSL (local high bandwidth server) is now around <5 ms.
It’s like being on the LAN if the server is on fiber also.
