You can collect a player ears when you kill him, but you have to wait a full day for 'em to grow back on his clone to get another pair in case you kill him again.

The squish sound of stacking ears was one of the greatest parts of D1.

+1 only if we get a squish sound

..No.

Would it be more acceptable with player panties instead of ears?

Why not? It's not like he was asking to collect their naughty bits. +1 if we get a trophy room added to our PDA as well.

How about like.. ship.. parts or something. I dunno. Helmets?

Ears is too far for me. There are a few too many real-world cases of this. I think it would also exceed our age/content ratings in a number of countries, some of which are pretty sensitive to this kind of thing.

Seriously helmets would be great. I didn't really take the OP seriously thinking it was intended as a jest and was amused at your response.

Even named scrap metal would be fine.

Would the trophies serve any purpose beyond aesthetics? Since they are an item intended to serve as a trophy of your kill, they should probably be spawned in a manner where only the intended recipient can see them or pick them up initially. They should probably also indicate who they came from and have a nice decorative plaque or hand etching to indicate who performed the kill. Even without further purpose, once picked up for the first time they should be treated like any other item so that the burgeoning trophy market can grow.

Show me the bodies! Free your minds!

+1 To trophies of some form. Sentience Sequencers or some other do-hicky.

What if they only drop from players who have bounties, then you can present them for the bounty reward and still keep them after, or maybe they drop from everybody but you have to turn them in to get bounties, it would make bounty hunting more of a thing and also someone has a chance to steal your bounty before you turn it in.

+1 to Viking's suggestion!

+1 Viking. The only thing I would add would be that this also include enemies of the state at a lesser reward - say 100,000 cr per distinct enemy kill per day.

This would also provide a way to put bounties and verify killed. Just put a timestamp on the helmet with the name.

a) A war trophy ( helm ) is dropped for bounty kills. The trophy is unique, with the name of the victor and the defeated, time stamp, and location.

b) the war trophy has a resale value at all stations, equal to the bounty.

you can keep the trophy, or you can sell it at a station for the bounty, but you can not have both.

No need to get fancy, some of us just want trophies that have meaning to us, that we can maybe show off somehow. Named scrap would suffice. Vacuum frozen heads would be better, but that is not possible. Transponder units, perhaps?

At the very least drop a helmet after a /duel. This would popularize dueling again.

+1 to trophies for duels. Helmets or scrap metal or whatever.

Would it be more acceptable with player panties instead of ears?

Another case where the squish sound would work.
