I like minigames. I'm talking about browser games where you can only control a computer mouse. For example, here https://mr.bet/game/view/demo/wild-toro I have been playing lately, these are demo games, but they give an idea about real games for real money.
The original 4 games are THE best in the Sonic The Hedgehog series.
I think Sonic 2 and Sonic & Knuckles are my favourites though, Sonic 2 for the nostalgia and the music plus Wing Fortress Zone and Death Egg Zone, oh and the bonus zones were fun too!
Sonic & Knuckles had great music, Knuckles who could fly obviously, new power boxes for Sonic, Metal Sonic and some awesome levels notably: Flying Battery Zone, Sandopolis Zone, Lava Reef Zone and Death Egg Zone! : )
I think 90-100 hrs is the most ive done on anything. That would be BoTW and Persona 5. Ive done a couple of run throughs on stuff like Skyrim and New Vegas that would probably amount to roughly that combined too.
Usually I start to get bored at around the 40 hour mark with most games.
