>>20351286In gen 1 where first impressions are everything, grass was easy-mode, which gave it a babymode connotation. Venusaur wasn't as "cool" as Charizard, wasn't a version mascot, and wasn't used by Red and Blue in any non-game media.
Chikorita looks stupid and is possibly the worst starter in existence.
Treecko was A LOT better but wasn't as broken as Blaziken and Swampert.
Turtwig, also awesome, but, enjoy your 4x ice weakness.
Snivy a shit.
Chesnaught is probably the only one that managed to pull off being cool and useful without having a crippling weakness.
TL;DR: The typing is shit. There has never been a grass starter that was unequivocally better than the fire/water starters.
