My friends have invited me to go to Combo Breaker with them, I'm not that good at fighting games and want to do at least okay for this convention but I've never really been to one, idk if I need a certain kinda controller, or how etiquette at this kind of thing works I'd appreciate any advice. The games I've played are Tekken 8, Soul Calibur VI, MKX, and Sparking Zero
