Single Player Offline Option

Nah, that’s not what I said in thst sentence at all. The implication is that they would have less people in their online environment, engaging in the community Blizzard interacts with. That that would cause the game to be a failure is what you are saying. I said it would fragment the player base. Don’t put words in my mouth.

Also, if you are arguing that fragmenting the player base would mean the game was a failure (quote 1) and then acknowledge that the playerbase would be fragmented (quote 2], then you are the one arguing mods = failed game.

Quote 1.

^ If the playerbase is fragmented, Blizzard will not receive as much attention or it will cause players to leave, both could cause the game to be considered a failure.

Quote 2

^ Fragmenting will happen no matter what, even if they don’t add mods, but definitely if they do

I still play Diablo 2 and there are are still tens of thousands of players playing at any given time on classic B Net. Perhaps Diablo 2 has kept itself alive on its own merits, and not because of mods.
