So, since I rushed the OP to get this posted quicker for star dust, I'll actually expand on my answer a bit more and talk about all 4 since I've played all of them for this event! In order from most to least favorite:
Mario Party Superstars: Mario Party's always a fun time. iirc, this is the 3rd time I've played it in a TBT event (and 5th with TBT users overall), and it's always been a blast each time I play it. I think the nature of the game combining some skill and mostly luck does make it fun to take part in and not get too upset if you end up losing
even when you have to commit crimes to take back what's rightfully yours . I just hope we can arrange more Mario Party sessions outside of the events, since they've definitely been far and few between.
Mario Kart 8 Deluxe: I do love the Mario Kart series a lot, and even though I was late to the party on picking up MK8D, I definitely made the most of it since then. It's always fun for me to play! Being good at the game has helped, but I'm definitely not trying to be ultra competitive, win every time kinda deal. I just stick with what works for me and try the best I can, and it's helped me have fun even when I struggle. I've had some neat moments during it, like the constant Baby Park picks and my friendly rivalry with @/daringred_ lmao
Super Smash Bros. Ultimate: I have a weird love-hate relationship with Smash. Like, I'm okay at the game, but fighting games haven't been my favorite genre of games and I do get constantly beat up by the better/more experienced Smash players on the forums, so it can be discouraging
especially since, honestly, I just don't want to put the effort in to get better lmao. I've at least made it more fun for myself this time around by just continuing to meme as Peach on stream and even trying out Olimar for a change.
Splatoon 3: I have very little experience with the online mode of Splatoon 3. Like I completed the story mode months ago, but that's been it. I definitely feel outmatched compared to a lot more of the experienced players on here, but it's fine! I've still had fun playing it and hope I haven't made anybody I get teamed up with too upset they have to carry me
Also, thinking about it, maybe there's something that can be said about the mystery stream tomorrow and whatever we end up doing for it. At least I have the ability to put that in as a poll option, lol.
