The racing book was a step in the wrong direction (and a rip off) as was the ridiculous xp boost pack. Even gaming sites slammed them for how much of a rip-off it was and they deserved it.
Let's hope! I think the fear is the connotation of the standard it sets. Is it just a matter of time until we have other stat tracking mechanisms that cost money and have useful gear tied into?
The XP boost pack to me just screamed of praying on the ignorant. It was literally the cost of TTK itself (standalone) in Canada.
