With the 0.3z release I was thinking it would be a good idea to store death information in the database:
killerProfileId (if any)
victimProfileId
deathReasonId - see http://wiki.sa-mp.com/wiki/Weapons - this can include the weapon used or the way the player died, eg drowned, splat, etc
timestamp
isLameKill - lame kills are defined as driveby shooting, carbomb killing or heli kills - this can just be a boolean.
I think this would be really interesting data to store. This would make it possible in the future to monitor things like favourite weapons, favourite/worst victim, etc. It could unlock a lot of cool new features that could be added in the future like extra bonuses for killing worst enemies.
MrBondt was concerned that this is a lot of data to store so perhaps we could use this thread to discuss it.
EDIT: Maybe we could store the position of the death too
EDIT2: And bodypart
