What is your Main Game you Focus most on Speedrunning or usually only Speedrun? Mine (at the Moment) is Pikmin 3 Deluxe, still I am training Little Nightmares 2 Speedrunning and I want it to be my Main Game.

I don't think I will ever have a "main speedgame". I don't have enough patience to play only one game for a long time, and also there are many other games out there.

Mine isn’t on the site, its a scratch game called “Appel”

Game(s) I'm focusing on right now are: Tim_, Frog King, and 60sbr
But for over a year now, my main game has definitely been Mobility!
Across all of the categories, I probably have 3-4 thousand total attempts, and I have several hundred hours in it. Even though I've taken frequent breaks from it, I still have a long list of goals for the game left.

Currently focused on learning Skate 3 and Omori (whenever Omori releases on Switch some time soon)

But my main speed games are the Outlast games.

My current focus for speedrunning is Disneys Tarzan, but I've also invested quite a bit of time on Spiderman 2000, Pepsiman and Digimon Rumble Arena.

Tough to say if i'm actively Speedrunning the campaign of LevelHead. Since it has a ton of user-build Levels, i usually play them and end up optimizing setups/strats or outright cheese their level to stand atop the in-game Leaderboard... Only to get beaten the next few days.

KH BBS.

currently learning Adventure Forward 2, been playing Speed Run 4 for over 2 years

I've been having computer issues that have largely prevented me from running anything so far this year... But when I finally get a new laptop, the first thing I'll do is start working on my fresh batch of cookies for Foxbot. I'll have to match or beat all my IL times if I want a proper record of my SoB!

Ehh, I switch around depending on my mood.
I'm currently learning Pokemon Sun, pretty much have the first hour of the game memorized, 5 more to go.
I'm also interested in learning Sonic 2 with Knuckles since I love Knuckles as a character and Sonic 2 was my first game
And when I'm just being casual I practice Wii Fit U obstacle course

Slime Rancher is my first and only main speedgame (so far).
I've been actively running it since August 2018. I've taken a break recently but I'll pick it back up again soon since I can still push my any% glitchless time much lower.

Mario Kart Wii has been mine since 2018, although I also play Mario Kart Super Circuit.

Streets Of Rage 4, although I'm trying to get more into platforming this year.

My main speedgame is Adventure Forward 2: Points of Conflict, however I have gained interest in Super Mario 64 ROM hacks.

My main (because only one because i started a few days ago ) is The Lost Cube.

My main speed game is Buffy The Vampire Slayer on Original Xbox, but i like to speedrun alot of other games. I'm a variety speedrunner just like my friend @Jaypin88Jaypin88

The Warriors is the only game I speedrun but I want to start and learn the GTA category extensions (San Andreas LS and Badlands chapters) at some point and also sleeping dogs.

It used to be Minesweeper for me, but my current interest is Zeek the Geek.

I speedrun Skylanders: Swap Force. Slowly working on getting 2:13:xx RTA for All Story Levels, Wii, Easy.

Open Season (GBA) is another game I like running. I should get back to it.
