Is it even worth it?
I didn't really enjoy JoH because it was so slow. As with the main game. Yes, there is story there, and its interesting, but its gated behind not only Power, but also slowly shuffling around in large spaces. JoH avoided the Power requirements by instead making you shuffle back and forth in vertical space.
Honestly, despite my love of DA and my previous purchase of ALL DLCs (yes, including armour/wep packs)...
I need to know Descent is good to even want to play it - let alone pay so much for it. Otherwise I'll just read a synopsis online, or watch a play-through at high speed, to save myself all the trundling and chipping away and massive health bars. I can have games on my Steam wishlist cheaper than this.
Honestly, being in a situation of 'ehh' about experiencing new DA content at all, regardless of price, surprises me. But I'd need convincing that the experience is worth it. Not just the story itself - but the actual combat, the characters, the atmosphere. Because if I DO eventually get back into DAI, doing so without mods will be even less appealing, and I doubt Descent is something that plays nice with the Mod Manager (at least not without a lot of kerfuffle).
