Ah, PvP. Personally I kinda hate it, even on those rare occasions when I manage to emerge victorious. In small doses it's OK, but usually it consists of getting face-rolled by a player who knows the game systems much better than I do. That said, minigame PvP is quite enjoyable, particularly Age of Conan's variety, as well as the scenarios in Warhammer Online.
For a carebear like me, the only way to make PvP even semi-palatable is to grant control over when and if it happens. Sure, we may still lose and provide a good belly-laugh to the seasoned killers who view us as their game content, but at least they're not barging in on an otherwise productive session of questing, crafting, or exploring.
What about you, Massively readers? Do you prefer your PvP in spurts such as minigame instances or battlegrounds, or do you like the open-world FFA option common in games like Darkfall and Mortal Online?
