Quoting Shanti & Tay:" LeapFrog LeapPad2 Explorer is what im looking at..is that the same as first one but more stuff included in the system"
LeapFrog makes both the LeapPad2 and the Explorer, but they're two different systems.
LeapPad2 is very similar to the original LeapPad, with a few extras/improvements.
Explorer is actually a set back. They now have the Exporer GS which is an upgrade on the Explorer itself.
