Celestia is a calm, collecting person who likes to joke around from time to time and doesn’t let her emotions rule her. She seems like someone who could take defeat well and still joke around. (She’s also been around for a long time and watched over the progress of the games.) She’d probably troll people, but not to the extent of making them quit or anything. More along the lines of friendly irritations.
Luna…Well, going by the show, she seems very serious, no nonsense, and has the thing of letting her emotions get out of hand/hoof. Yeah, she was more jovial in the Big Mac comic, but she comes across as someone who’d prefer outdoor activities then just staying indoors and playing some confusing new invention.
