The Legend of Spyro trilogy are underrated gems, and deserve a re-release to current generation consoles as a bundle of all three games. 

The Legend of Spyro trilogy has gained a cult following over the years, but sadly is the only Spyro series not getting any attention right now. 

The Classic series is getting a remaster, and Skylanders is still going, but TLOS series is left in the dust. 

Also it is hard to obtain the games these days, and they never made a bundle of them, you can only get them one at a time, which is annoying considering the story's all tie in together. 

Also a re-release could fix some of the problems with the games, such as the difficulty, and replay value.
