On one hand, this is a really great post about PvP from the perspective of someone with that K orientation who wants a PvP-based game. Syncaine makes all the points you would want about why someone wants PvP with consequences and who the niche is, with the awareness that it is a much smaller market than the PvE theme park I am currently trying. Even if you consider PvPers and Killers some foreign species, the post retains great anthropological value. It does not need my help to recommend it.
On the other hand, a lot of it comes down to “the niche is even smaller than previously realized.”
On the gripping hand, it is potentially the No True Scotsman fallacy in motion. The PvP game must be “well-executed” (grant the potentially tendentious claim that Darkfall is), which is the most common excuse for why the last five PvP-centric games failed. Players who quit did not really want meaningful PvP, because they cannot take losing to people who are better than them. And hey, both may be completely true in this case, but that becomes an increasingly narrow edge on which to balance as “the niche” gets defined down to an increasingly small population. Many players on that edge will bleed into the Fundamental Attribution Error: if I did not like the game, it was poorly executed; if you did not like that game, it’s because you are a whining loser noskillz carebear. I imagine someone on the Darkfall forums has made a hobby of tracking players’ moving from the second claim to the first as they ragequit.
