My all time favorite game is Minecraft. I have been playing this game since 2016. I also like Forza Horizon, Gods of War, Assassin's Creed and Final Fantasy
I wouldn't point to one game being one that is exciting the way that I look at it. However, playing Top Eleven Football Manager for years has brought me immense joy despite losing some trophies along the line.
The Sonic the Hedgehog is my favorite gaming franchise in general, but my all time favorite hands down is Sonic 3 and Knuckles. I love how each character has his own paths to take in each level, heck I just discovered a new path that I never usually take in one of the zones in the game. (I honestly can't remember the zone off the top of my head but I was baffled that I never took the path before...)
