I really love all the features implemented with that stronghold. I find it utterly exciting and it gave me some thoughts that others already mentioned, except for the last one :
- I also loved the ideas that you can make use of equipment that your party doesn't fancy anymore, to melt Iron or equip your guards for Instance.
- To be able to custom your castle with loots/exploits/prisoners/trophies that your party valiantly fought for is also neat. No way you don't bring back the head of that huge dragon you just vanquished to your stronghold if you are an adventurer !
- A stronghold would be great if you could organise events such as jousts, fairs, political receptions or balls or weddings useful for a broader plot in a mission ! It would be an investment to organise such events, but could bring revenue, or prestige. That beast you just captured might do the show, or maybe the joust could be an other way to prove you're still the best fighter in the area if you are willing to join...
