[Guild]
Customizable Ranks and Titles (Guild Leader could create ranks, titles, and modify privileges for each rank.)
Renown System Changes
1. Increasing awarded renown for faster progression. (Will seriously benefit smaller guilds.)
2. Adding more levels (Creates more content for larger guilds.)
3. Level Rewards Tweak (Larger guilds will earn more renown, so make rewards at high levels more relevant to large guilds who are likely to be pursuing a larger amount of game content. Vice versa.)
Take a look at City Decorations
1. Some are very small and not worth a centerpiece slot.
2. Add more slots to the city, and more decoration recipes.
3. Add a small decoration slot that spawns on the inside of buildings.
Temple Upgrade Choice (Crom, Set, Mitra. Base on city location.)
