I was thinking that games which have a chance to earn money sometimes don’t have very many interesting things to spend the money on, this makes the game boring more quickly than it otherwise could be, this was one of the good things about Oblivion, Robin hood and Guilds 2.
I am thinking that not only should there be inventive ways to earn money but also inventive ways to spend it.
To begin with there could be the ability to buy businesses:
Blacksmiths, bakers, stables, farms etc. where you could work in them to earn a bit of extra income and/or set the production and hire employees.
I also think religion could be represented such as the ability to become a Knights Templar to go on religious quests like collection of money for the church, destroying bandit camps, acting as a banker? This could also be one of the guilds that could be joined, along with merchants and mercenary guilds perhaps? You could then progress through the ranks and become the guild boss, helping your influence and renown grow throughout the kingdom.
I am wondering if it could be possible in game that you could lead a double life as a kind of robin hood type figure. This would mean setting up a camp in a forest or cave and slowly improving it. This would be done by paying for materials and could become another source of income as more people join your camp, the calibre of these people could depend on your actions, i.e. good actions would bring honourable people with different abilities and vice versa. This could also allow the character to ambush tax collectors and caravans or army platoons that travel through your domain. It would be especially good if you would have to defend your territory from other bandits and the king’s men and if you could take over other bandit camps as well as sack villages and eventually castles. Related to this there could be a chance to join the king’s army and progress through the ranks e.g. peasant, footman/archer, sergeant, lieutenant of foot (where you would have your own platoon within the army and during battles you would be given tasks to complete, such as capture a flag, attack supply caravans, destroy siege equipment), horseman, horseman sergeant, siege equipment operator leading to general/knight and eventually duke, where along the way you would be given land, villages, houses, weapons and various trinkets. It would be interesting if you could choose which part of the army you could fight in for different battles and you could become skilled and proficient in that area.
At a higher level there could be a general rank system where you could start as a peasant and end up either as a high lord or king and your ability to do this would depend upon the amount of land and money you have procured through various means and how many followers including the size of your own private army that you have recruited from villages, towns, brigand camps and other places that may or may not be under your control. It would be good too if you could commission to be built farms, houses, bakeries, market squares, taverns etc. all of different shapes and sizes which you could lease out to peasants, traders and dignitaries and you would have to protect them from danger from your castles and barracks.
I am also hoping that at some point there will be water travel and combat i.e. boarding ships and sea/estuary invasions of ports and towns?
Finally I am thinking that extra income could be used to invest in a scientist which could provide upgrades and new technology. Such as higher quality metals used for armour and weapons which could be lighter and harder to damage which you could equip but could also equip your army/guild units with. Also prototype cannons, telescopes, armoured chariots, deployable traps, crossbows etc. used for your armies/guild units and also upgrades for your villages and castles could be researched like tiles, mounted crossbows, better walls and roofs.
