Gab I'd rather see it as a mega patch then a DLC if it's going to offer game improvements. If it just going to add additional items and companions then keep it a DLC.
IIRC if the new content is big then Microsoft and Sony forces the developers to put a price tag on it.
So I dunno
how it would work or
if it would work but if we can't have it patched in like regular patches
then I think this would work for the best.
I just think that they should spend their time fleshing out the real game instead of giving us mini-games for 8 bucks.
If the only way is to scoop all the new main game content up and release it as an Update Pack #1 DLC then I'd say go for it.
I think it's better than
no main game content at least.
