Reason number, like, a hundred billion or something in the list of reasons why I don't play online multiplayer games. Not that I ever want to play competitive multiplayer games at all, even if I did otherwise play online multiplayer games, which I don't.
Also, it's something that wasn't touched on in the clip above, but an extension of that is why I don't ever want to play online-only-even-for-singleplayer games, either. If a """""server"""""" is telling me I didn't do a thing in a game that I clearly saw myself do in that game on my own computer, or vice versa, then that game is fucked up and I don't want to play it. (But, really, it's more the "no, you can't play your singleplayer game right now because the servers are down and you can't login and we stupidly don't allow you to play this singleplayer game offline" type of issues that make me never want to play online-only-even-for-singleplayer" games.)
(EDIT) It reminds me, again, of that stuff I talked about with Interstate '76, though that was a direct result of a shitty multiplayer system that calculated things client side rather than server side and allowed egregious "hacking" simply via modifying some non-encrypted text-readable config files, but it's still the same sort of issue.
