It's interesting how the rams meat quest gets brought up in regards to "rping" and motivation. Not saying that it is seen the same by all, which is obvious, but here was my take on this, and a few thoughts regarding what the DA franchise might look at, in regards to TW3. Sorry if this is long winded.
Regarding MotivationWe are told before we set out for the Hinterlands, that we should be making a presence for the Inquisition, helping where we can (which can influence the public), closing rifts (since the IQ is the only one capable of it, due to the mark), and finding and recruiting "agents" (which is all our PC is, at that time). After helping out at the crossroads, when trying to meet with Mother Giselle the first time, we get a cut scene with her. We are both shown and told what the general peasants are facing. After the cutscene finishes, Cassandra pipes-in about Corporal Vale heading up the Inquisition camp at the Crossroads, and that we should talk to him to find out what help they need. Going to Corporal Vale reveals that they are lacking on food, blankets and healers, and indicates who to speak to (or in the case of healers, where to go - i.e. Redcliffe) regarding these matters. End result, should you fulfill these quests, you gain influence from the people in the region (Mother Giselle points out in dialogue how much things have improved due to our efforts), and you gain agents under the leadership of Corporal Vale (though only Vale gets listed as an agent under Cullen's name in the WR).
So motivation, can be found just in what the game gives us, but a player can also choose to add further motivation, based on how they have painted their protagonist. Much of it may end up as headcanon, but that is something I crave from these types of games. I love having the wiggle room to add my own little side stories and motivations, to my PC's. That may not be everyone's cup of tea, and that is certainly fine. But I am grateful to have games that do allow this.
As for why someone may choose
not to complete the quests (or even seek out Corporal Vale), it is certainly easy to imagine an Inquisitor who has "prioritized" certain matters. For them, a more pragmatic approach might make more sense. Setting up camps, getting the quartermasters horses for the troops, making the roads easier and safer to move troops through (i.e. stopping the skirmishing mages and Templars), and closing the rifts within the area.
Feedback for DAI have now played TW3 and have very much enjoyed the game. I am happy to parrot others with some feedback regarding the following:
1) Connect the maps to the main story more effectively. The Hinterlands, Crestwood and The Western Approach, are the only three that did that with requirements to move the story forward. The Storm Coast did this to a slightly lesser degree, by putting both the retrieval of a companion
and their personal quest, in said zone/map. And there is some reason (if you chose In Hushed Whispers), to venture to the Emerald Graves and Emprise du Lion (Cullen's string of quests that can help against Sampson). But, again, it isn't required.
2) Cinematics. I am one of those that doesn't wish for quite as many cut scenes as there are in TW3. I really didn't need up to two or more cut scenes for a Monster Contract. Simple reason being, is that most of the cut scenes didn't really offer anything. It was simply random person, says they need Geralt to slay or investigate something, and Geralt accepting and possibly haggling on a price. Generally, I just felt that it stretched out what was often a very short and easily fulfilled contract. I admit, for me, I wanted those to be a bit "speedier", considering the number of them, along with all the
points of interest marks, on the map (which were more often than not monster nests, guarded treasure, and bandits).
However! I do agree that there should have been more cut scenes per zone, and they would have been well received if they were quest lines that tied into the main storyline. Even if the quest in question is short, punctuated. I also think that there should have been a cut scene for each of the Keep leaders (for Crestwood's Keep, Griffon Wing Keep, and Suledin's Keep). Having a chance for our PC's to get up close and personal with said Keep leaders, might make us feel more "attached" to said Keep and region. And give us more of a reason to return for quests. This would also lead to some quest receiving restructuring. Captain Rylen's quest list, I think was very well structured. The others should have been set up more akin to that. IMO.
Some addition of cut scenes (similar in presentation to what TW3 gave us), and the overall connectedness of zones/maps to the main story (again, TW3 did a great job with this), are the two main things I would love to see in the next DA or DAI DLC.
Again, sorry for lengthy post. Cheers!
