Veering between BG3 and DA4:
BG3-I wonder if everything (whole game) had been included in the EA, the quality of all three acts would have improved, not just Act I (which I enjoy most)?
DA4-I watched the gameplay trailer yesterday. It didn't feel like a game, it felt more like a Make Your Own Adventure book translated into a movie instead of a book. Was that just me?
For your first question, about BG3, I don't know. I tend to like act 1 and 2 more than act 3. I consider the EA alone a good spending of my money, no matter the criticisms I might have had in mind with the full game. I imagine that, yes, having been able to work like that for act 1 in EA, with feedback, might have helped a lot. But it was also the start of the game, the story, a narrower scope. I find act 2 very good too, maybe because it's still very focused, on Ketheric and Moonrise. Same for the revelations and objectives, I think. And the totally different atmosphere is nice. Would the rest have benefited from the same EA treatment, maybe. Would it have been possible, don't know. The writing and the ideas for how to bring things in motion and to conclusion are important. I find act 3 more all over the place, and I don't know exactly to what extent feedback could have helped there.
For DA4, I don't know what to say to you (it's very subjective ?), but no, I didn't have the same impression. I mean, I kind of understand what you're saying, but not that much in fact. Different tone, visual style, and choice of point of focus to expose, but I, for example, don't find it too dissimilar to the trailers for BG3 I've seen. In that it felt movie like with its editing from scenes from the game. Emphasis on you as the hero (like the one with Jaheira talking), and cue to funny moments (I think it's in the same one that there's a poor flying Barcus with an Astarion comment). As for the Make Your Own Adventure book reference, well, at least it's on brand ? I really didn't mind it, honestly. And I like that they focused on Rook and his companions for the Veilguard. It allows to take a look at various places we'll travel to, at various factions we'll meet, and to recall some lore, through them and their segment. While emphasizing on something that many people enjoy in a DA game, the group of people you're facing things with. At the same time, it doesn't go too in depth regarding the plot, which is not a bad thing in my opinion. But, at the same time, I've played the previous games, enjoyed them, and read the short stories and comics in between. So that might influence my perception of things, and it might be difficult to get something out of the trailer otherwise.
