Somewhat of a duplicate reply here to another thread...
We have noticed as the organization has been sending various teams to WFH,
an increase in bandwidth to our various VPN services. It's been creeping up
daily.
we are in process of upgrading our bandwidth to these areas to support this.

Playing games doesn't take much bandwidth. Downloading games does. So
as long as everyone already has their games and there's no updates,
playing the game is typically under 100 kbps which is negligible
compared to streaming video which takes 1 to 25 mbps.

My experience at $job[$now] (IXP) and $job[-1] (ISP with residential
users) show otherwise. ISP-side traffic comes inbound from ASNs hosting
gaming platforms, and IXP-side, gaming platforms have no issues taking 100G
ports and pushing lots of traffic on them. Ratio-wise, they seem very much
"heavy outbound". When new games are released, we see extra traffic from
CDNs. Even if a game does not generate much traffic, in a MMO context every
user pushes one data stream but receives several ones. And there may be
reasons (avoiding cheats) where traffic pushed from the gaming platform
contains more then each user's actions.
IMO, it depends on how game handles inter-player communication. I do
recall playing some serverless networked games some 15-20 years ago, with 3
players each on their own ADSL or cable, and the upstream (in the 512-800
Kbps range) never getting saturated.
