taken from that skylander boy and girl video it seems that the vehicles only get supercharged to certain characters, so if you plan on investing in a character, expect to buy their vehicle to fully be capable of what they can do. the video around in other sections shows how much storm blade can do with hot streak until spitfire uses it. so each combo is going to set you close to 30 bucks to be effective. the fact the game is more or less just walking and driving is kind of a turn off. that gameplay could have been accomplished without the gimmick. so in a way the skylanders can't go through every section unless you put a vehicle on the portal. im a bit down you can't actually place the skylander in there, that's a bit of a downer. stormblade looks good and maybe spitfire but the gameplay is not something i like
I think we have found the catch, and why they won't let you get away with only buying two extra vehicles.
