Transparent as possible? The audacity Not a single mention of it prior to the game's release.
I think the importance of the leaderboards are simply over estimated. I don't really remember anyone giving it much thought besides for the trophies in DR1. Building the Community Events into My Team was also merely a choice, not a necessity.
I'm not going to endlessly reiterate myself like some, but I'm glad I held off my purchase and reassuring that I won't even consider buying DR2 now. This is coming from someone who owns every CMR and DiRT game, including two copies of DR1 for each console.
