First one is Red, I doubt you will get a lot of people that will say anything besides Red/Blue/Yellow.
Funny story to go with that, I remember playing Red and choosing Bulbasaur as a starter. Since my English wasn't very good at the time, I was wondering what "Release" meant when you were using the PC. Out of curiosity, I pressed "release" On Bulbasaur and ended up confused to why he (?) was gone afterwards. Also, I didn't beat the first gym, which means I only had a Pikachu and Pidgey. I restarted my file afterwards and chose Charmander and beat the game later. But that's not the end of it, in Gold, while fighting Red, I had the most trouble taking down its Venusaur despite having a fire starter because the Venusaur would usually be the last one to die.
