You are right. it is the defining statement. This entire thread is opinion.
Let me make this simple. This entire tangent started after I attempted to show the difference between Ubisoft's always online DRM and Blizzard's always online "DRM". There is a very staunch difference between the two, and it irritates me to see them clumped together like two peas in a pod.
Sometimes, I use the term "MMO" or "MMO Lite" to describe how Diablo III works. The game
literally sends your commands to the server. The server will decide whether the command is valid or not and update the world (your character, NPCs, enemies, environment, etc.) accordingly. This information is then conveyed back to the player. This is just what World of Warcraft does. This is why I make the MMO or MMO Lite distinction. This is why I try to separate this always online requirement from Ubisoft's always online requirement.
Actually, a better way to put it is that calling it a "MMO Lite" saves me from having to type all that shit above.
Ultimately, I am ignoring your opinion in regard to this tangent, because it is irrelevant. I don't care if you don't like how Diablo III was implemented when we're discussing how the implementation is "like a MMO", and how that differs it from Ubisoft's always online DRM.
Yet can't answer the problem of 'If always online' only some people get what they want. But "with offline mode, everyone gets what they want."
If an offline mode were introduced, one would assume that the players would be unable to use the in-game auction house. If a significant number of players used the offline mode, they would be unable to sell their gear/items on the auction house. Isn't it possible that this could affect all "pro-online" players?
How about you and everybody else that's "anti-online" answer this question: how many waking hours are you unable to play Diablo III strictly because of an online-only requirement? To make it more interesting, separate non-maintenance and maintenance times.
Do you really suffer because of the game's always online requirement? Also, even if you have been forced to not play it... is it really that great of an injustice?
