I heard back on the subreddit that Polybius is still being tried in different mobile phone games. Anecdotal maybe but my personal story is a game called Antiyoy. A simplistic medieval style hexagon board game where your goal is to take over all other kingdoms.

After my second day of playing it (I didn't play it that much) I started having dreams and nightmares revolving around this game. It was like I was playing the video game entirely in my hyper-realistic dream (I never have hyper realistic dreams). It was becoming scary, after a week of playing the game only during downtime, my dreams started revolving around this, all night, different strategy after different strategy, ways I had never tried before. It's unlike other "video game dreams"; this was almost exactly like I was playing the game except I couldn't choose not to play it. Deleted the game and effects immediately went away.

Does anyone else feel this with this game or have a similar experience with a different game?
