Everyone should be able to game. Gamers for Giving is a charity group that aims to make that happen. They raise money to provide gaming setups for kids in hospitals, as well as provide money for other gamer outreach programs. From March 20th-21st 2021, they'll be hosting a virtual gaming marathon to raise money for their cause.
If you'd like to help out more, you can start your own fundraising campaign to support them here! If you raise enough for one of their mobile gaming stations, they'll build and ship it to the hospital of your choice!
