you want the truth? probably not
I believe they don't decide WHEN to put up new games. The games will contact Gamehag when they need some more people on their game. Gamehag will get paid in real money for each of their users that completes the tasks, until the game says it's enough.
It's possible that the game publishers say "We need 1000 new and real people to play this game. We also want new players to see that we have players who actually play the game, so we need them to reach level 45 on a new account, so that the people that find our game won't immediatly turn away because it's filled with lv 1 players that joined and immediatly quit."
I don't know exactly how these deals are made, but I'm pretty sure that Gamehag wants to see more game tasks offered, much as we do, since they'll get money from us, who are doing the tasks.
