The four games I mentioned were:

- SteamWorld Dig: old west robot prospector (ForestC was right!)

- Coming Out On Top: a man have sex with a giant goldfish, a gay college student coming out to his parents

- Escape Goat: get a mouse to wear a hat, a goat that's also a political prisoner. It's more about the goat than the mouse, but I was afraid that "Play as a Goat" would make people think of Goat Simulator. Plus, I found the magic hat to be adorable.

- Long Live the Queen: consoled a grieving child, cope with the death of a parent

I'm interested in the games he listed as well. I know the first one (robot prospector) is probably SteamWorld Dig. Not certain about the others.
