Well, I got the game at release and played through it twice, but unfortunately my PC at the time died shortly after. Finally got my new PC built back in October and I've been playing Inquisition again since the DLCs went on sale recently.
I liked the game well enough when I played it originally, but I really love it now. The story DLC is just so good, absolutely top-notch, and an example of how to do DLC right. Descent and Trespasser in particular are amazing. Descent, because the Deep Roads, Dwarves, and Darkspawn are my favorite things in this franchise and the way the Deep Roads were shown was absolutely stunning. Trespasser was just awesome all around and helped by the fact that it too had a Deep Roads section. Both DLCs expanded on the lore and answered old questions, and had fantastic music to boot. I was excited when it was announced Trevor Morris would be doing the soundtrack and I wasn't disappointed, especially in the DLC. The Trespasser changes to the skill trees and the addition of trials are great as well and have made the gameplay much more enjoyable to me.
Beyond the story, the absolute best thing they did in Inquisition was bring back race options. I'm so into elves now it's crazy, as I previously despised elves in the last two games.
Now for the negative bit. The ending of the main story always felt rushed and out of place to me; the fact that Corypheus can show up on your doorstep and has the power the raise basically a mountain into the sky opens a whole can of worms that I won't get into. I'm disappointed that the potential of a siege on Skyhold is never realized.
The tactical camera feels incredibly awkward to me compared to Origins to the point that I just don't use it. I hope in the future this goes back to the Origins/DA2 model where issuing commands top-down or OTS are the same on PC. The lack of AI tactics is an enormous problem too. The AI simply can't play certain specs, nor can it capitalize on combo finishers. In previous games I mostly controlled party positioning. I don't like to micro manage ability use so it'd be nice if the AI can do a reasonably good job on its own. I hope in the next game tactics make a comeback.
Customization: The Skyhold wardrobe helps a bit, but I'd like the option to not be tied to one of these finery outfits at all and just use my armor. In Origins I kept a a noble outfit handy, mostly for meeting the nobles in Vigil's Keep. I would prefer something like this just so I had options. Even the other Skyhold outfits aren't much to look at. Further, on the subject of clothes, why do female characters have to look so mannish with their clothing? I have the formal attire specifically in mind here. Wearing the formal attire and dancing with Florianne is one of the most awkward things I've seen in a video game. Lastly, there are several nice armor skins in the game that I will never use because they are simply leagues behind upgradable armor in terms of power - this is also why I don't have the Avvar or Qunari DLCs because I just don't see the point. I'd love to see a system that separates stats from appearance in future games. Also, less trenchcoats and maybe a proper robe skin or two would be welcome.
Mods: I'm no expert on modding but please, Bioware, if it's possible make the next game more mod friendly. What the modding community has been able to accomplish is impressive, but I wish we could see the kind of support for modding that Origins had or at least DA2, which would take care of the appearance vs. stat suggestion I made previously. Mods are such a boon to PC gaming, and honestly if it weren't for mods I don't think I could make a female character in Inquisition that I'd be happy with.
Romance: Obviously has become a big part of BioWare games. While I can, and have, skipped romance I'd just like to state that I think the options for heterosexual male characters are lacking. DA2 had options, unfortunately just not the one I wanted (Aveline) but in Inquisition it feels like Cassandra is the only real choice, at least for me. She's great and I love the bits of humor involved with her, but other than my devout Andrastian warrior I wouldn't pursue it. Josephine is another human who is mired in human things, and I'll just come out and say it, she's not attractive. I played a male elf recently and I felt like I had 0 options, so like in DA2 I didn't romance anyone. When I play my dwarf it'll be the same story.
I'm not saying there has to be a follower for everything, but maybe allow for more non-follower avenues. Harding is great but nothing comes of it. Flissa pretty much comes out and says she'd bang when you talk to her as a human male, though you're given no option to explore that; it's just left as an awkward moment. Not to mention that Inquisition is the first DA game to not even have a brothel (which my Hawke who pined for Aveline had to use). It's odd to say it like this, I know, but I'd like to see a straight, female dwarf that you can really romance. My dwarves deserve love too. If not, then please bring back brothels.
Anyway, sorry this post got to be a bit long. I wanted to put my thoughts out there since I'm coming at the game again fresh, but I didn't think it warranted its own thread.
