Because Red could easily be confused with the Red paired with Blue rather than the one with green.Don't forget that Japanese Red Version was similar to Green Version, so why do peolple always just say "Green Version"?
What exactly are the differences in green? Just different sprites or are there gameplay changes?
Pretty much the same here. I didn't care enough to try Green after Yellow came out. Besides, Yellow was really cool all by itself. In my opinion, Yellow could have been the only Pokémon game released at the time and I'd be content.I was interested in playing it. However, I never truly pursued finding any means of being able to play it. Yellow was amazing enough to not really care enough to try out the Japanese's third installment.
