Okay: New and improved roles.
Malatium has been reworked to show the alignment of the player who targets a player targetting the user, and instead shows who that alignment person targetted.
Electrum still shows role+identity
Steel and bronze both give instant info (role/alignment) and give additional info the following cycle on the same scan. This is to discourage quick-claiming.
Zinc and pewter have been swapped for flavour reasons (which speaking of, I have a theme in mind for this game; it should make sense).
Aluminum now exists to make scans less certain.
Only atium and nicrosil affect your target's target's target.
Turning atium into a reliable scan is quite hard already. Say, if you try to coordinate it, it only takes one aluminum misting or one coppercloud order from the previous cycle to stop it. Or you could get gold-blocked or bendalloy blocked if you aren't careful. But atium having such a long chain actually makes it more easy to avoid all these rb countermeasures.
Malatium has been fixed. It should also be noted that you can't tell if someone targetted you or not (they don't ned to publically declare their target) and there could easily be another person targetting them that you could target by accident and show up on the malat scan.
PMs on/off will make a big difference to the game. Its essentially completely different game without pms. I think I am leaning more towards PM open, since I want people to actually try to utilize these roles to their fullest.
I think ultimately the distro especially on elim side influences the game a lot.
