Here’s what I’ve picked up so far:
- Her Story
- The Beginner’s Guide
- Risk: Factions
- Rust
- Gabriel Knight: Sins of the Fathers (20th Anniversary Edition)
- Quake Live
- Downwell
- Black Mesa
I’m sure I’ll add a few more games before the sale ends. A friend of mine gifted me some Steam dollarydoos, so half of them were free!
Update 2016-01-06: I apparently played it conservative and didn’t buy any more games during the Steam sale.
