Only played the first game so far as I haven't played the other two.
I'm impressed with how much fun I had given it's Spyro's debut, controls are smooth as butter and I enjoyed how rather open-ended the game overall is. Though, at points it's rather hard to get the right altitude with the gliding to reach certain places, and I have to admit I wasn't a fan of the flight stages with how strict the time can be and how punishing it feels when Spyro hits something and stops flying. The game, however, never forced me to deal with these and I managed to finish it by skipping some of them, which I'm thankful for. Feels like skipping the more annoying missions in Mario 64.
The remake's quality, though, is absolutely fantastic. Visually one of the most impressive remakes I've seen this generation without a doubt.
