I would like to add my two cents worth here.. from two perspectives...
First as an Admin Owner of a group of TAE's I want to provide my members with the best value for money for their advertising that I can.
Since the NoPayPal fiasco I have had to rethink my sites and again it is about my members so I instigated extra promocodes because I
could no longer provide paid advertising.
As a user of several hundred TAE's since around 1995 I look for good click thru rates on my advertising I still believe in good rule of thumb
that a site needs to be visited at least 7 times before most users will sit up and take notice, I do not think playing games on a TAE is the
best way to go as it detracts from what the TAE is there for.
If I want to play games I will go to a games site rather than use up my credits and time on a TAE playing a game.
