>>11880530>>118822362 and 3 are objective downgrades in almost every aspect 1 excelled at
Spyro 1's levels were almost entirely large open spaces with lots of hidden spots to find and a focus on platforming and gliding long distances.
Spyro 2/3's level designs are almost entirely linear, and the game is more focused on "beating the level" and completing objectives than anything else. The focus on platforming is mostly gone.
Spyro 1 allowed you to fully complete a level on the first visit, so you didn't need to keep backtracking to levels you've already done just to get one more thing that you couldn't before.
Spyro 2/3 added in extra unlockable moves and alternate characters, respectively, just to force you to backtrack and pad out the game's play time with tedious busywork. All of the alternate characters are slower and more boring to play than Spyro himself.
Spyro 1 didn't have any minigame bullshit, just a handful of Flight levels that were fucking kino since they gave you free flight which wasn't allowed elsewhere in the game (save for one level)
Spyro 2/3 added tons of tedious minigames, often making you play them twice to fully complete them. Spyro 3 took it even further, straight-up ripping off other PS1 games because the devs were running out of ideas.
They're not bad games at all, they're just very different from the first game. Spyro 1 is a 10/10 while 2 and 3 are 8.5/10.
