I've reached Act 3 for the 3rd time now and I think I'm able to articulate how I feel about it. Having done it already I know the sheer amount of content involved but at the same time I still have that feeling of urgency pushing me to the final battle. Meanwhile all the decisions and companion quests pending are overwhelming. It's like "alright it's time we do X, kill Y, retrieve Z, go solve this thing and on top of that we're having a huge ass battle''
The one thing motivating me was getting to know Minthara because I recruited her with the new method and I really liked her. But I've lost my motivation with her broken romance. I'd like to get to experience the ending and epilogue with her but I don't know if it's worth doing it now or waiting until she's eventually functional. I already had the bug with the skipped scene at the end of Act 2 and it was a downer.
Although it's hilarious that when you have both Halsin and Minthara they share the same spot in camp and their tents are just mashed together in one franken-tent.
I think I would prefer if it was spread into 2 different Acts or 1 interlude and a final Act and the content was more organized and easier to follow. Every time I get to Lower City and see the 546 quest markers it feels like trying to clean a really messy house and not knowing where to start. Also, and this is more subjective, from a roleplaying perspective I feel alone in Act 3. Everyone is focused on their own thing or not responsive at all after dealing with their own quests. I just wish I could sit and talk to somebody about what's happening and get some kind of comfort or friendly word. But I just get the Emperor trying to manipulate me instead.
I think I'll take a break and wait until there's news about a dlc, definitive edition or patch that shakes things up a little.
