She won't push any harder - her work here is done. She got her name attached to a problem that she "solved"- all that's left is for her to pull it out during the 2008 campaign to show everyone how powerful she is and how much she cares about your kids (gag....)
Don't forget, the game developers and the rest of the entertainment industry will probably be the largest group out there bankrolling her campaign after George Soros. She won't want to push too hard and risk pissing them off. As far as the industry goes, they'll be happy to let her have this cheap little symbolic victory if it helps the cause, just like drug smugglers arrange to have the corrupt cops on their payrolls make a few cheap busts so they can parade their success in the media and keep their jobs.
GTA has been the best selling game all year I believe. RockStar will be very upset if this game goes sour.
I believe that they are already working on a new edition. This game will be a year old this October.
