My daughter will tell you that Spyro is life. She loves unwinding with these games and she loves that she can play Skylanders on the go.
What I like about the DS versions of the game is that you don't have to lug all those annoying action figures around. After you load them on the portal pad the first time, the game saves them to your current save file so you don't need it or the portal and can play even if you don't have them. Plus, the portal works with all the standard action figures.
