Someone please lock away my wallet, as the GOG Spring Sale is live and it's full of discounted Linux games.
For this huge sale, GOG are also doing Flash Deals so every 24 hours a couple of games will get a higher than usual discount so you will need to keep going back for the best.
As usual, I try to be somewhat helpful and so I've picked out a bunch I think are probably worth your time and money that are on sale currently:
- Sphinx and the Cursed Mummy - 67% off
- Paradigm - 66% off
- Shadow Tactics: Blades of the Shogun - 60% off
- Torment: Tides of Numenera - 50% off
- Tyranny - 50% off
- Figment - 49% off
- Surviving Mars - 40% off
- Iconoclasts - 35% off
- Neverwinter Nights: Enhanced Edition - 33% off
- Hand of Fate 2 - 25% off
I would recommend Stellaris too but it's actually cheaper in the Humble Strategy Bundle 2019.
