I play breath of the wild, regrets are "troll and I" along with "has been heroes". They were titles I grabbed without looking up gameplay first. Always check gameplay before grabbing a game if possible.
I played Zelda the most, hundreds of hours, and will play again when the 2nd DLC pack drops. These days I mostly play NeuroVoider while waiting for MORPHITE and Axiom Verge.
I never got splatoon 2 yet but I got Mario Kart 8, Disgaea 5 and BotW right now. Dont regret having any of em because I dont make the stupid choice lf getting a game I dislike. Research first, play later.
I own Zelda and Mario Kart, but I never liked the Bomberman game. Lol I've never played the others though so maybe they're better. Botw is always my favorite. Mario Kart 8D is fun to play with friends but otherwise their aren't enough unlockables to keep me playing by myself
