I do this in all games... singleplayer or multiplayer, RPG or RTS. I can't stand black areas on explored parts of the map...Anyway... I was mostly talking about quests and missions. For me it brings a new dimension to the questing to have people with you while you quest. Especially if they are interested in talking a little and using tactics etc. But I can see that partying with people that rush ahead, never say a thing and ignore other partymembers more or less is worse than going with NPCs. But compared to going with people that try, and want, to help each other... that's what I'm talking about.
