I adored the Sly Cooper trilogy as a kid. I played through those games multiple times and they left a lasting impression on me the likes of which Jak never did (never played R&C as a kid, surprisingly). But recently, I replayed through all three of them again (fuck Thieves in Time) and...god. This is one of the jankiest series' I've played outside of Sonic. I was shocked at how genuinely bad the hit detection was. There were many, MANY times where the cane decided to just stop working for no reason. All 3 of them had problems, but Sly 3 was the worst. Without even mentioning how many gameplay gimmicks Sly 3 introduces (few of which are good), it was easily the buggiest. At one point, I even fell through the floor. No wonder it only took a year to come out. Above all else, this series taught me a lot about context sensitivity and how toxic it can be to game feel.
The writing is also cringeworthy. I remember this series's writing being great, with a strong story and genuine character development. Decent storytelling and character development are there, but they tend to be shoehorned in at the last act with little buildup and little relevance to the rest of the game. And the humor...if you can even call it that...geez. R&C is still genuinely funny and witty to this day. Jak has its cringe moments, particularly when it takes itself seriously, but it also does a good job with its humor and it never feels juvenile. Sly on the other hand does, and is just painfully unfunny.
This was a shock to my childhood. Finding out the Sly games were never really that good felt like finding out Santa wasn't real.
