I never did mention my most loved characters this gen so here goes:
-Majima and Kiryu, both of these were awesome in the last couple of generations but only got even better this generation. Especially Majima in 0 and in his campaign in Kiwami 2.
-Mimir, like other people stated, head was an awesome idea and his dialogue is the best in the game. The voiced novelization of the game is worth it because he is narrating it.
-Kat, what else is there to say? She is the best part of the game and it makes me sad we might never get a third game with her. She deserved better.
-G, best newcomer in Street Fighter 5.
In terms of like, an overall popular pick, I'd sooner see people go with Ellie than Arthur for what this thread is about.
Are we talking about the character being lovable as a character trait or how loved the character is in the player base? Because if it is the former then I agree but if it is the second then I disagree because everyone I talked to loved the character, even those who hated the game. I have no hard proof on how many people liked him so I could very well be wrong.
