I like PvP in games that don't have a really noticeable progression system. Like, leveling and skills and all of that + permadeath.. I don't like. Like, I love playing DayZ even if I get super anxious about it (always paranoid about dyin'). I had fun in Nether which mixed a strange levels system but you could get to max in 2 hours or so, same with DayZ - you die but you can get back where you were very soon.
