Since this is a strategus suggestion, I thought it would fit here more. If this is the wrong place, feel free to move it.
Right, as of now, we have renown that does...well, nothing. chadz has some basic, good, ideas of what it should do, however alone these ideas could create an imbalance.
The original suggestion was for renown to increase troop recruitment. That is a very good idea, and I would like to start with that. It should certainly do that. For example, it could increase recruitment by 10% per 20k renown or so (rough numbers). However, this leads us to a problem: old players simply get a big advantage over new ones.
There is a way to solve this. Make renown also a resource. This means that give players a way to "spend" renown for big short-term benefits. That way players will (usually) not just accumulate huge amounts of renown but instead spend it thus keeping it down to reasonable levels.
A few ways renown could be spend (again, rough ideas)
-forced march: removes exhaustion, replaces it with a full time quick march again but doubles the exhaustion twice afterwards (can't be used twice in a row).
-surprise attack: give defenders less time to prepare for the attack.
-recruitment drive: increases troop recruitment by a huge % for a day (make it worth it)
I am sure you gentlemen can think of more. Ideally, most players will want to at spend a big part of their renown gains but not spend it
all as soon as they get it.
The second part of this suggestion is about trading. chadz said he wanted to give renown for trading. That is, in my opinion, a mistake under my current suggestion. Instead, renown should be for millitary combat only. Traders should have a different resource, let's call it "fame".
Fame could be gained by...well...trading. Unlike renown, its benefits should be to trading itself. So, fame passively will decrease weapon and good prices but then can also be spend on various things.
-bargain: reduce prices for weapons and armors by X big amount for a small period.
-logistics: weight from goods will temporarily slow you down much less
-hide cargo: will stop the enemy from taking a percentage of your cargo in case he beats you.
edit: -kind of silly to forget this. <insert appropriate name for selling stuff more expensively> : you sell stuff more expensively for a small period of time (surprising effect, init?
)
something cool I also came up with (but very unlikely to be implemented) is "caravan defence" where, when you defend, you start in a mini-fort made of carts.
This would not only help make the game more deep and interesting (at least until the gr...certain clans decide to abuse it :3) but also help strategus specialization. While everyone can technically still do everything, clans will want to have dedicated traders and warriors in their ranks which would make for an interesting dynamic.
edit: to be clear, you
spent your renown. Once you do one of those special decisions, you lose said corrensponding amount of renown.
