PC Number Limits for Quests

[SN]

To be honest, the more people you have with you on the quest, the easier it is, the more 'time' you have to actually RP throughout it as you are less focused on trying not to die...

I always liked 4-5 PCs max on a quest and more seemed crazy, unless the quest is to fight an invading army or assault some sort of stronghold.  It's great to involve people but having 8, 9, or 10 PCs out with you is a bit silly in most cases.
