Yellow was based off the Anime, so pikachu was novelty.
Was it that hard to make a few more sprites to give us a walking Raichu?
Yes, because Yellow Version was based on the anime and that Pikachu never evolved. So yea, that's why you can't have a walking Raichu in Yellow.
^ Really? I mean, I personally LOVED Red, but I think Yellow had a better concept honestly, with the option to get all three starters. I woulda loved Yellow a lot more if the colors weren't so iffy.
It's not stupid to use a weaker Pokemon. Pikachu actually isn't that bad. Although back then it wasn't that great due to the lack of Light Ball. But still, Yellow followed the anime and it was just a novelty thing to have it.
And who doesn't enjoy that little thing following you in the overworld? >.<
