Really glad that Pokemon Blue/Green won! It's the game that I started with, so that's my choice. Moreover, siding with Marie proved to be worth it.
In terms of equipment, getting two same sub-abilities that is not a likely ability feels worth it, let alone three (which I didn't get, of course). Last time I got a Samurai Jacket with them, but I thought re-rolling them was a good idea, but I regretted it. Recently, I got two Swim Speed Ups on an FC Albacore, whose main ability is Damage Up with Takoroka (High chance of Special Charge Up), but was a little disappointed at the Inkling Speed Up at the last one.
Thanks for reading.
