Um it did just launch two days ago and the ones that have to do with the site are just the same kind of ones that are across the other wiskey media sites with quests. The reason the scavenger type quests aren't as plentiful probably has to do with the wiki not being as full compared to say Giantbomb's wiki, which probably has to do with most of the people on here being not as obssessed with the ordinary wiki points as they are on the site and the smaller user base.
I'm going to take a guess and say it's highly likely there will be more quests that involve hunting through the wiki in the future. It's just things take time.
"I am aware that animevice's wiki is the least updated out of the wiskey sites, so I understand why so many of the quest have to do with the wiki. I guess I got spoiled with Giant bomb's quest and how much they actually had to do with videogames, even when they were first released. "
Those had to do with searching through their wiki as well.
