I was pretty silly when I first played R/B.
It was my first time having a Gameboy, like most I'm sure, and I actually didn't really notice that there was a Start and Select button. So for like a few days, I didn't know it was possible to save. I would just continually restart, training up a new team and going through the beginning over and over. I think the farthest I got was just before Mt. Moon. I had figured the whole time there should be a way to save, but accepted that maybe there wouldn't be a way because I was a big Sonic fan as well, and Sonic 1 and 2 don't have any saving system at all. Let me tell you, I was amazed upon hitting the start button and seeing "SAVE." XD
I didn't really understand the PC system (I didn't know what withdraw and deposit meant and, for some reason, never though to look it up), so when I put Pokemon in the PC, I pretty much assumed that I would never see them again. Y'see, I tried "withdraw" first and when I saw it did nothing (because there's no Pokemon in the PC), I went to deposit and learned that it got rid of my Pokemon, and then just never checked out withdraw again. Making my team ended up being these huge decisions that I'd have to mull over. XD Again, withdrawing Pokemon out of it blew my mind.
Hmm... what else... Oh! I never nicknamed Pokemon because I had some strange idea that naming the Pokemon can end up changing what species it was. Or something. And upon trying it, and seeing it didn't change the Pokemon, I was still afraid because I thought that the Pokemon wouldn't evolve anymore because it was stuck with the same name.
Andand! I assumed all the stat up and stat down moves didn't do anything. I mean, I didn't see any visible affect so because of that, they obviously did nothing. XD
Poor little me. =[
