yes and no? my first game was technically yellow, but i lost it and my gameboy before ever getting past brock. i played the N64 titles between then and gen 3, but those don't rly count lol but my gen 2 was basically pokemon stadium 2 while everyone else played GSC. anyway my next game was sapphire which i did get past the first gym leader lol and beat it so tho yellow is where i started, i kind of consider sapphire my first game bc i got to really experience it. but emerald is my favorite. so? take that how you will ig
fwiw i really enjoy yellow it's not my favorite but i do enjoy gen 1 for all of its weird quirks, ugly sprites, and the music. like i could still play it fine and enjoy myself if i popped it in rn. and if you know me you know i live for RSE and have played all of them more times than i would like to count lmfao. so in both cases, the games hold up really well for me.
