To be honest, I think they bit off more than they could chew. They wrote an epic grand story but didn't have enough time to put it all together.
Yeah, I mean even with the extended 18 months, a deadline is still a deadline and from the PAX Demos, you could see there was a ton of stuff they wanted to included that they had to cut out because they simply lacked the time to either get it to work or had to focus their attention elsewhere?
I'd have taken smaller areas with more lore, than vast areas with very little plot-relevance? When you consider that most areas in the game are larger than all of DAO and DA2 combined, but compared to how much story those games managed to fit into it, I think we could have traded some of that open-world for more immersive story?
As much as I love DAI and ME3 and think they're great games, I do think Bioware has had a problem lately with trying to one-up themselves in each game, only to run out of time and leave us with a hastily rushed ending? We don't need an epic, we just want a game with an ending and denouement that actually lets us wrap the story up nicely, rather than being over in five minutes and leaving us wondering... "Wait, was that it?"
While DA2 was rushed overall, at least everything in the game came to a head in "The Last Straw" and the ending didn't come so much out of nowhere. The last Act was shorter and suffered from a lot of disconnect from the previous two in some ways, but the Mage-Templar thread still had been building over the game so it didn't feel so far out of the left when you got to it?
Overall, the games need less filler and more thriller... better pacing and less racing?
