I've never really been too interested in Spyro. I played a demo once a couple of years ago but other than that i haven't touched it so i'm gonna withhold my judgement on the game. They look like they might be a good series, i just skimmed through a couple of reviews for some of the games and they all got decent reviews.
I consider Spyro to be an excellent game, as I'm very partial to dragons, and this was the first game I found where I could play as a dragon.
I to like dragons, in fact, they're my favorite out of all the mythical creatures and yet i've never played any of the Spyro games or Reign of Fire before. Speaking of dragons in games, i think theres a game coming out for the ps3 where you get to play as a dragon. I think its called "Lair".
