Personally, I've watched many of my friends replays, I can use 64x speed if I want to skip a good chunk of an area, I don't fairly care if someone uses mods, I tend to not use them as I am still new to this game.

Replays are not that huge, just upload the save game zip file? They are not huge at ...

I don't get this, people will upload their videos but what I really want to watch is the replays of the games instead, upload already!
