Lol, what? So how exactly are "expand on the game already existing" and "adding to the core game" different again? Generally a patch fixes bugs while an expansion adds them--er--adds new content. In reality though, they're both the same. Boxed expansions fix bugs, large patches add content...differentiating them in any meaningful way is silly.

If Aventurine continues to offer free expansions, kudos to them; finally a company doing it the proper way (nod to CCP as well), IMO.
