Want to help people and buy games? The Hurricane Relief Bundle on itch will help you do just that. It has a few Linux games in it too. I think ideas like this are great, I couldn't imagine the stress and heartache from having my house destroyed by such furious weather.
It costs $20, of which 100% of the profits go to these charities: GlobalGiving Hurricane Irma Relief Fund, Halo Foundation, Partners in Health (Haiti branches) and Direct Impact Fund for Hurricanes Harvey & Irma.
Check out the bundle here.
It's being hosted by developer loren schmidt, who says they will be as transparent as possible and give regular updates on it. I also think it's fantastic that itch.io gives developers the ability to do things like this!
