Bored Ramblings II: Object of Importance

I've been replaying the older Pokemon games and I have to ask this:

HOW THE HELL DID WE EVER GET BY WITHOUT UNLIMITED INVENTORY SPACE?!

Seriously, in Gen 1, you only had 20 item slots, INCLUDING KEY ITEMS. This wasn't fixed until Gen 4, OVER TEN YEARS AFTER POKEMON RBGY's RELEASE!

Sorry for overreacting, but that's bullshit.
