Second Love Letter. You can learn to play in 10 min, a game is over in 20 min, but you'll play for hours. By name, it doesn't grab you (me, anyway,) but I genuinely don't know anyone that doesn't like it. Also, Sheriff of Nottingham

Both of these break the traditional mold, are crazy simple to learn and are way more fun than they have any right to be.

Do you by any chance write for Black Mirror?

I tend to be pretty privacy-conscious and one of the reasons I haven't up/downvoted much is that here on kbin.social, at least, your votes are very transparent. If you go to the 'more' option under any post and click on 'activity' you can view exactly how each user interacted with that post. The only time I'll currently interact with a post is to save it to my profile (or comment like this w/o identifying information.) I think all of this might be a major hurdle to some people.
