I've said this numerous times on any forum from any game0 I have ever played, "If the player is given his or her own base of operations; upgrades in all possible areas should be available." I find it rather pointless adding in such a feature, like Skyhold and be given little to do with it. Or have a ridculious option of choosing between building an Infirmary or a Sparing Ring. Uh (knocks on Laidlaw's head) hello! There not even using the same location!
If you ever played "Pillars of Eternity" or Neverwinter Nights 2, both of these games gave the player the opportunity to upgrade from inside to outside the base.
In DAI the resources are there but the developers did not implement it.
We have: War Table, Endless amounts of materials such as ore, plants etc and filling requisitions.
What should the developers done?
Place an NPC in the lower section of the castle as a Treasure. His/her job is maintaining not only the income of the Inquisition but also the resources.
So with this NPC this is how it could have been laid out.
Enter a zone and get a Requisition. You need X amount of Elfroot to resupply the Infirmary. Fill the requisition. Once you fill it the order disappears until it needs X amount again. If don't have the Infirmary built it won't show up.
The walls of Skyhold need to be rebuilt. Since you completed the War Table mission in helping to deliver materials to Sarnia. With the reward of 2 tons of granite, you have enough stone to build the walls, but the Inquisition needs to have the money to pay the workers.
At any time the Inquisitor can head down into the basement of Skyhold and check the book to see which resources and money are need or just a general idea of the numbers.
This would allow money, resources and the requisition table to have more of a purpose.
And, no this is not Sims. It's something that many MMOS or single players game have offered to the players. It's called: utilizing the tools the developers have given in order for the player to feel more engaged with the game world and have a small hand in building it.
If Bioware added in a DLC pack just to allow the above to happen or something similar to happen, I would not hesitate to buy it.
Your building an organization who should have a fortified stronghold to match. Instead Skyhold is nothing more than an illusion of a stronghold. Kind of like seeing how pretty a house looks on the outside and go inside and see rats and cockroaches holding hands and dancing to gawdful techno music. While the floors are completely rotted out, water spraying every where and the air smells like a grandmother's panties that have not been washed in months.
Skyhold came off as one of those half-ass jobs. Like the developers wanted to give you a nice stronghold but had very little incentive of allowing the player to really let Skyhold shine as a true base of the Inquisition.
