Started replaying in prep for a friend of mine (VegaBaby) planning on streaming Sonic the Hedgehog (2006) later in the month for zeir roughly yearly charity stream the game again and... I genuinely really enjoy playing Sonic '06. It is a deeply silly experience. The game is so fundamentally broken that every minute or so something completely ridiculous will happen like Sonic's corpse flying self-propelled off to the horizon for no explainable reason in unpredictable fashions. Throw in some goofy cutscenes and general weirdness and it's all like curling up with a schlocky movie I'm fond of.
It's also fairly unique in that starting in the 360/PS3 generation, high profile broken games tended to get patched so that all the ridiculous bugs were no longer as omnipresent. Like, the Wii U Sonic game known for an infinite jump exploit got that infinite jump exploit patched out. Sonic '06 was left untouched in all its "spinning on a box causes it to levitate" glory.
Admittedly, I am playing with infinite lives hacked in and from an SSD on my PS3. It'd be a lot more frustrating without those... and I'm still not looking forwards to the Ancient Egyptian Billiard Ball Puzzle.
