For each game individually, I got all Skill Points to unlock the Art Gallery and played all the bonus levels available.

Spyro the Dragon - 120% in 7 Hours 30 Minutes.
Spyro 2: Ripto's Rage - 100% in 9 Hours 10 Minutes.
Spyro 3: Year of the Dragon - 117% in 10 Hours 40 Minutes.

I vividly remember playing Spyro 1 as a child, and had just as much fun with it as I did back then. The upgraded graphics and engine for the Reignited Trilogy really improved the gameplay IMO.

I don't remember playing Spyro 2 as a kid, but it was just as I expected in a sequel. The addition of the character Moneybags that you would have to pay gems to unlock new abilities was an interesting choice. I could tell they added it just as a way to force the player to backtrack to levels they have already played because certain areas were not available without these abilities. It stretched the gameplay out in a way that it didn't need to be, it added MAYBE an hour of gameplay.

Spyro 3 I have very vague memories of playing, specifically playing as Agent 9, and I want to say that it was from a demo version of the game. But with that, the addition of other playable characters was a big jump for the series. Sheila the Kangaroo, Sgt. Byrd the Penguin, Bentley the Yeti, and Agent 9 the Monkey were very great characters with very cool abilities. Most of the time these characters were locked to their own levels, but the would help during the big boss fights, and I can remember one instance where Sgt. Byrd was able to fly around the main area of the level instead of Spyro. The addition of the two different challenges in the Speedway levels was a lot of fun, and added more depth to each of these levels.

I did have some minor issues with collision detection and floaty controls throughout these games, but I also played on mouse and keyboard, where the game was designed with a controller in mind. Some areas and specific challenges were very frustration, like the Yeti Boxing and Hunter's mission to shoot the Cow UFOs in Country Speedway. These did give me some trouble, but slowing down and taking my time did make these a bit more bearable. All in all, these are great games that still hold up and are still a very good time.

Gulp fight is cancer and the man who made the skill point connected to it needs to be investigated as they cheat for Gulp beyond all reason. Its a cheat and even bigger than the original shame to everyone connected to that boss fight.

All 3 games are fun from start to the end.
Even collecting all the gems was fun, even though this isn't usually my thing.
