You can have multiplayer influenced worlds and environments, enjoy seeing what others do and create in that world, without enjoying the partying up aspect. MMOs with competitive markets, faction influencing, or competing with players in general rather than direct conflicts.

Then just don’t answer? Why is it so hard for people to understand that just because I call doesn’t mean you need to answer. You’re busy and will respond later, that’s what voicemail is for.

I don’t understand why people think a call has to be answered.
