Your second reason is exactly why I think the impression of Geno differs so much from person to person. Unless you consistently used him in your party, he kinda just disappears for the rest of the game.Geno left an impression on me because,
A.) He was the first entity in ANY Mario game to imply a deeper lore; this entire concept of the stars being part of some kind of divine hierarchy, which continued in things like Paper Mario, Super Mario Galaxy, and more.
B.) He was easily one of the best party members battle-wise. Peach is a great healer, and with the Lazy Shell, Mario is just as good as Bowser at single kills. Geno is the AoE mage, and he’s the best at that role. My preferred team is always Mario, Geno, and Peach.
Maybe I'm not looking at him the proper way, but I never see the same character people are describing whenever they talk about Geno. Even in his own game, I thought he was outclassed by other characters like Booster and Mallow. He's not terrible or anything, but aside from his generic "I'm a levelheaded tough guy here to protect the world" personality, there isn't really any part of him that would make me say he was memorable.
