I like 3d platformers and open-world games and LOVVVE gliches, what game should i play?

Well, I don't know what consoles you have, if you are willing to spend money, or how long you would want runs to be, but I'll give a variety of suggestions:

Minecraft: This one is pretty popular to run right now Mario 3D World: Now that this game has been ported to the switch, it's easier to get than ever. This game has a lot of really interesting speed tech, glitches, etc. Karlson: Very short, fast paced fps platforming game. Rayman 2: Incredibly buggy and glitchy masterpiece, a really fun game but the any% run incorporates several incredibly difficult glitches/tricks.

Minecraft is a very fun game, but can be hard to speedrun. personally, I prefer to go on servers, such as Hypixel and CubeCraft, and speedrun there. My favorite thing to do on Cubecraft is to speedrun its parkour. It's a lot more fun then you would ever think

Hey, welcome here!

In terms of open-world games, even if I don't know what platforms you're playing, you can try the game series theHunter. Ofc, also Minecraft which is the most active game around here.

Have fun!
