Hi all,

At the moment, Crossfire's shops aren't particularly useful. For
medium-level players, prices seem unreasonable, while new players can't
afford to buy from shops at all. Old players with high charisma and
bargaining, on the other hand, don't notice a huge discrepancy.

The shops (and economy) in crossfire have many problems, many have been discussed before, so I won't restate them, but I think any change is just going to be one piece of the puzzle.

The attached patch attempts to fix some of these issues:

Charisma and bargaining now only affect the shop buy price, with
multipliers ranging from 2x for new players to 0.5x for very advanced
players. This is consistent with rogue-style shopkeeper greed but still
better than the existing situation. Bargaining is now significantly less
useful; the hope is that in the near future it is replaced with
interactive "haggling".

If you are going to reduce the importance of bargaining, is there any reason to just not remove it all together then? The passive skills were always a little odd (passive skills being those that the player just automatically uses without any effort, and likewise, can't really focus much on improving them).

I'm not quite sure how interactive haggling will work out - it will seem like someone would pretty quickly figure out how it works, write a plugin to the client to just do the work and get maximum value, at which point, one asks why not just skip all those steps and just give the player the best price to start with.

I do think that having stats & skills affect buy price is a good improvement - high level players tend to have more money than they can do anything with and never buy anything, so therefor, don't really see the advantage.

The sell price is clamped down to 0.5x base price, subject to additional
shop specialization and greed. This sell price is mostly better than the
existing prices, and at the very least prevents high level players from
buying and selling for a profit.

One thing to be absolute sure to check is that it is never possible for a character to sell something for more than they can buy it (eg, buy for 100, sell for 101), because that clearly breaks the game. In fact, even doing it equal would probably break the game.

For those not looking at the patch, it appears to be that the character will get best price if their charisma is 30 or they have maximum bargaining level (or some combination in between (level 20 bargaining and 25 charisma would appear to do it also)

I'd personally rather that instad of shop_buy_multiplier() having a hardcoded formula that is used, that is instead stored in the stat_bonus file, and if not set there, perhaps fill in the array based on that formula.

I'm not sure how many people actually use the stat_bonus file, but all the code is there so it is a pretty simple matter to just keep using it - at also lets player admins adjust things more easily (with the formula as is, it is pretty much impossible to adjust things - at least with the old compiled in arrays, one could change those to get different behavior)

 Otherwise, looks good to me.
