I'm new to running, I just did my first run a few days ago for the Monster Hunter: World beta! I have a question also about speedrunning; is it weird for someone to speedrun only one game? I have an interest in MH:W running, but not any other game. If I were to start streaming/uploading runs, would that be looked down upon by the community? Thanks in advanced!

Hello! Not at all. You can do whatever you love here. Everyone speedruns differently. Some of us just go around doing all the categories quick as we can, some of us strive for decent runs and then move to the next. I'd say I fall into that category. Then, you have the world record holders. Take abney317 or cheese05 for example. They've been running the same game for over 3 years now. With that being said, no! There is nothing wrong with doing that at all!

Welcome. I hope you have fun here.

I wouldn't say that is a bad thing if you enjoy it you enjoy it, if you don't want to speed run other games that is perfectly fine :) and welcome :D
