I love super fillers. I characterize these as games that you can play in under 45 minutes but have a lot of quality deep decision space.
I don't really care if there is a learning curve or not.
An example for me would be #Race for the Galaxy. Once you learn it, and there is a learning curve, you can easily whip out a game in inner 45 minutes. If you are playing two player you can play two games in 45 minutes. But there are a lot of bigger longer games that don't offer as much good decision space.
What are your recommendations?
