I've finally gone and done it. I completed the dex in all four gen 1 games simultaneously. Took me months of playing and a shitload of trading and a fuckton of Stadium 2 management.

My final teams for each, with me preferring to use any exclusives I could, were:
>Red
Charizard, Vileplume, Electabuzz, Nidoking, Cloyster, Kabutops
>Green
Venusaur, Persian, Sandlash, Starmie, Fearow, Electrode
>Blue
Blastoise, Jynx, Exeggutor, Nidoqueen, Aerodactyl, Golem
>Yellow
Dragonite, Raichu, Venusaur, Charizard, Blastoise, Alakazam

Some notes:
>Yellow sucks ass.
>I wanted to use Magmar in Green, but couldn't come up with a moveset, and I didn't think I really needed Fire anymore by the time I reached Cinnabar.
>Didn't do any glitching, hence no Mew, and the only ingame trade I did was for Mr. Mime, since they fucked up really hard and made that the only way to get it at all in gen 1.
>I had been planning on using Machamp in Red and Gengar in Green, but then I didn't.
>The MVPs for each game are Cloyster, Persian, Exeggutor, and Raichu.

The question is, where do I go from here, anons?
