Pokémon, Crash Bandicoot, and Bomberman. Tastes change from week to week and year to year.

Upbeat / zombie apocalypse screamo

My name is James, and I registered it. Isn't that exciting

A question of the most influential is entirely subjective. In terms of me starting out, I've enjoyed games for a long time. I'm 31 and consider speedrunning a pleasure alone. Love to compete, but wouldn't consider myself special. Its enough for me, a hobby

@jackziml Lol!

Bomberman, probably

Mobile (extra):

Bombergrounds Bomber Friends Crash Bandicoot: On The Run! Worms 2 / 3

Agree with what's already been said. Photos can be edited, same with videos. However, a video is favoured for inspection (in most cases)

Eat

Mods can upload their own runs, yes. If any of those runs are of significance (high up on the leaderboard), the community will soon verify the legitimacy of that run, if its a popular game. This is a community driven place, so any corruption will be sussed sooner or later, in that respect, for those that may think its wrong that mods verify themselves

Too hard to decide. Bomberman

I agree with the points made above. Overall...practice and attempting to improve existing strategies

As @bold said: Go fast

Hit up the relevant mods

The best is subjective, IMO

Unacceptable

When you submit a game and if it gets accepted, you're automatically a mod. As a responsible mod, you may decide on individual level runs / full game runs, or special requirements for uploads (probably not, apart from the run not being tampered, modified or cut)...list what you think is relevant

Scroll the net dude. You've got an internet connection, plenty free games online

Verification usually doesn't take long. As @Pear pointed out, need to keep the vids up to be recognised
