That might go a good way towards ensuring the, "about 300K units [needed] to make its money back," as Ninja Theory's Dominic Matthews told me at gamescom in an interesting chat about the tenability of big-budget, high-fidelity development. Hellblade is the team's first independent game and it is only getting a digital release.
I enjoyed chatting about Ninja Theory's aim for Hellblade and I enjoyed playing it as well, early state that is was in. It has some interesting ideas on a small, intimate scale, but with AAA-style polish. The team regularly releases development diaries you can follow if inclined, too.
