I am trying to get as many games played as I can but this is also a bad thing.
You are trying to get loads done in a short time so you tend to only play a few minutes of a game.(Less I guess if you get stuck or game controls are not obvious )
I try to play at least 5 minutes minimum but will play longer if the game hooks me. Unfortunately some games are just asset flips and i don't tend to play those too long.
Games like Oni-Powered I found myself coming back to a few times as it has a great repeatability.
