Why can't we pre-order--then choose a bonus content?
Challenge levels are fun--try dashing 100 meters in just 15 seconds without using the Force, Starkiller. Hard, eh?
More skins are always fun, especially when the modding community jumps in--but it's sometimes more fun (or plain annoying!) having to solve a puzzle or kill a godlike enemy to get the reward.
It's just that these gaming companies are competing. Why not just get the option to pick your bonuses if you preorder?
Come to think of it, wouldn't Lucasarts release a patch or two that includes extra skins and a few challenge levels? They sort of did that when they released USE.
They did listen to all the feedback, supposedly, so set up a loud call for this sort of patch and they might make it.
