I have been disappointed some many times in the past few years.
Shadowbane - flop
Vanguard - flop
Daggerfall - flop
My opinion is that any game with full on open world pvp will not attract enough mainstream gamers to be profitable.
One of the best pvp systems I have seen is in a game called Fallen Earth. Full on pvp is restricted to large areas of the maps call conflict regions(CR). All the best crafting materials are in these CRs. The CRs can be conquered and owned by player factions. When the CRs are not owned they have elite level mobs that control them. The incentive to engage in pvp was to have access to materials which are used in crafting end game gear. I thought it was a great system and still occasionally log in and play the game.
Crowfall - wait and see what it delivers. I really hope this game can deliver because right not I don't have anything engaging to play.
