What game has given you the biggest highs but also the greatest lows, mentally speaking?

For example, when I used to play League of Legends I would have such insane peaks where I just had to play another game because it was so much fun, but then some days I’d hop on and play an intense game for an hour and lose, and just be so down that it would affect my entire day in real life (for this reason I no longer play that game).

Has anyone had similar experiences with other games out there? Regardless of multiplayer or single player.
