1. friends nagging me to join their pvp while I try to enjoy single player
2. updates of a program that I don't need, I just want to play the game.
3. extra burden on:
a) processing power,
b) bandwith
4. time it takes to load game (first steam needs to load, then update/check for updates, before the game launbches)
5. steam requiers internet connection, even despite it being able to run in offline mode, it is not without a hickup
6. and that extra calculating power costs electricity, therefore it costs money, no matter how small, still it does.
In my opinion best anti piracy was implemented in Witcher 3.
I do hope TW will make a steam free version.
play steam offline, end of story its what i do 99.99% of the time
