I think the quests are really neat. I've discovered some great games that I hadn't played before in my quest for quests. Thank you everyone who worked on putting the quest system together.
I just wish it was easier to find out which quests I still need to complete. Like a page that shows only my unfinished quests, or marking them on the list of all quests like they are on the game pages, something like that. It's not difficult to remember which games I still need quests for now, but as more quests are added that's going to be hard to keep track of.
