the housing is a good idea, I ve made this idea in swtor, for space stations (not ships) for guilds and or wealthy individuals. But they always complain about resources... anyway.
The idea was.... I will speak for ESO (transformed)
Be able to have our own guild castles or towers for wealthy individuals... Just to have a castle or a tower is a boring thing... BUT IF.
1) this houses/castles can turn into a dungeon (with a kind of queue/request or guild wars)
2) the npc that the opposite guild or team will face inside that castle or tower, is the hirelings I will buy or rent to guard my tower or the castle, the hirelings can be modified with my desired weapons and tiers).
3) be able to decorate them and modify them the way we want, with traps, surprises...monsters
If the opposite succeeds to pass through and win my castle defenses, It has dynamic damaging system, I have to pay lots to repair, my hirelings quit and I have to get others, or dead... And all that, with great rewards!
The way to join these kind of battle system, it can be a kind of "search for battle" tab or an invitation, or declaring wars between guilds, that you can request a battle between guild castles, or individual towers (4 men for individual towers) and (24 men for guild castles)... Guild castles could even more surprising!! The final boss can be a massive 24v24 guild vs guild... panic...
