Won't we do that like for games:
a) download games list - it's just for display list of games to user
b) download game details - it's happening after user select particular game, we display game details then

I thought that we'll be doing the same for tasks:
a) download tasks list for particular game - when logged user select some active game, tasks list will be displayed
b) download task details - after choosing some task, there will be basic info about it and possible answers or map position
