Mother Series - Mistaken Order?

[J-bit]

Has anyone noticed that in Earthbound 1 (Mother 2) that electronics such as tv, cars, huge colorful lights were in that game, but in Earthbound 2 (Mother 3), which I think was supposed to be a sequel, had none? So no material in EB was used in EB2! So when the dragon in the end of EB2 came out to make the new world, you would think that EB came after EB2 because future technology was made.

Anyone got me?
