In a response to a question over on Bound by Flame’s official Facebook page, developer Spiders Studio confirmed that the game will be at least 30 hours long.
In the response they do say it will take 30 if you complete ‘most’ of the side quests, meaning that it could be longer for a full clear, but could also be shorter if you suffer from main quest tunnel vision.
How much shorter? No idea. The use of the word ‘most’ means nothing without any sort of context, but thirty sounds like a reasonable adventure, and a reasonable length proposition, without sounding like PR fluff.
All this but mere hours after Bound by Flame’s new music trailer (which you can view here)? We’re being spoilt!
