OLD PERSON CHALLENGE: re-install a game you can't remember playing

Here's the dare:

Sort your Steam library (or whatever library you use) by "recently played". Scroll down. Keep scrolling. Don't stop yet. Almost there, keep scrolling, aaaaaaaand stop. Preferably somewhere at least 3/4 of the way through your library. Find a game there that Steam says you've played for at least an hour but you have almost or entirely no memory of.

Install it.

Play it.

Report back!

Game played: Waveform

Last played: 2014

Time played: 70 minutes

Report: OK, that's a pretty neat arcade game that appeals to my inner engineer as your controls are essentially amplitude and frequency dials for a sinusoid that you manipulate to collect shinies and avoid bombs. I can see why I didn't play it more, it's kind of a one-trick pony.

Game identified: Space Trader Merchant Marine
Last played: Found beyond the section with dates. Achievements show unlocked December of 2009
Time played: 7.9 hours.

Report: As soon as I got into the game I remembered it. Some kind of a weird trading/economics layer on top of a clunky first person game with occasional battles against NPC opponents that swarm you.
Edit: And I seem to have failed the campaign right as I made enough money to pay off my ship. Not sure if there was a timer I missed or something, but it is making me start over. I might be done.

Steam says that I own this, and that I played three minutes of it at some time in the past. No recollection.

Be relieved.

Oh I love this idea. Tagging myself here so I remember to try this.
