Hi, I became a speedrunner a few months ago and then left the account, but now i want to do more speedruns, and I have a question: What should I speedrun? My friend reccommended me Sonic Forces, but i'm not sure. Thanks!

What kind of games do you like?

Random game suggestions rarely work. You can try pinpoint the games you would like to run if you specify game type/genre, range of run time length, etc, for better suggestions (if you know what you want, of course). Another general suggestions is to run games that you like to play, or played a lot before. This way you probably won't get bored of the game .

I played a lot of Minecraft (maybe 200 hours, idk), maybe I should try speedrunning it?

Of course, try it out!
