I think it's best to give a proposal in this topic http://armorgames.com/community/thread/11136662/games-you-want-quests-on We can only hope that one day there will be quests for a game like Sonny!
As far as I know Krin is working on Sonny 3, so ......
There are already quests in some older games, not super old as far as i know, but games like epic combo got quests and it was already out. (I think, the one they put qquests on might have been new). But anyways, i think the general goal is to make game creators include possible quests for a majority of new games, to make sure they come frequently. Games like "Sonny" having quests would be pretty cool though!
There should be quests for This is the Only Level 1-2 (3 already has some), Achievement Unlocked 1-3, and some other games of John's. There should be quests for John's more boring games (no offense, just truth, and by boring, i mean fast going ones as well), too, like Elephant Rave, Elements, and some others (would've said Coinbox Hero if it didn't already have quests :P). There ARE others, but quests would fix that. Would be nice if Obey the Game, Run, Elephant, Run, Elephant Quest, and LOOT The Game had quests too.
