Maybe it is just me and I do not understand the thrill of killing someone in a game who offers no resistance and has no chance whatsoever of being able to defend themselves, but, after 4 hours on the Darkscape worlds, I will be unlikely to ever EVER return to it.
Not just you. While engaging in pvp on Star Trek Online as I frequently did I made it a point that the easy targets wouldn't be targeted for the fun of it. You kill someone who is easy once, fine, but kill the more experienced people twice instead. In many ways it's like sport hunting, it's about the hunt itself and not just the reward. More people need to see that.
I hope DarkScape ultimately succeeds. If it succeeds we could possibly see some of the ideas back ported into RS3. After all, wasn't Ironman mode first on Old School? I haven't tried the game mode yet but there are some interesting opportunities aside from pvp. We'll have to see if people kill for sport or if they just kill and poach.
