The masses that are not in the community and who are suppose to buy lots of T:V will primarily be influenced by word of mouth and shelf appearence.
I think peachskins' box designs are great because
1) they have a clean appearence
2) they show interresting ingame photos right there on the front
3) shows what the game is about, makes you want to look at the back and see bigger shots and read about features
4) one for every class is smart because it will generate extra sales from the crazed tribes fanatics who have to have all the boxes, and its interresting that there are classes and that they have designs that are evident in armors/maps etc. which is enticing. However might leave out the first one to save costs.
