Yes, the Spyro's Adventure Portal will work on Giants. So you can buy the Portal Owners Pack.
Yes there is a new pack called portal owner pack it comes with the game and a figure
Your Portal from Spyro's Adventure will work with the Giants game. That is why Activision designed the Portal Owner's Pack. This contains the Giants video game, and an actual Giant Tree Rex. If you already own a portal you do not need the Starter pack for Giants.
Giants is the second game of Skylanders. Your current Skylanders can still work for Giants. There will be bigger figure and characters you can buy and new story.
yes...
Skylanders Giants is a different video game to Spyro's Adventure, however you can use your original Portal of power in the new game. Also, all Skylanders characters from the original game will work in the new Giants game. However, the totally new characters in the Giants game including all the actual Giants and LightCore figures will not play in the old game. Only those reposed series 2 figures produced for the Giants game, but we're also in the Spyro's Adventure game, will play in the original game. Check the packaging on the side of the new Giants figures and there is a diagram tha shows which games the figure will play in.
