I was thinking about something like this a couple of months ago. There are currently no gold/iron/bronze hammers that I know of that exist in FTF but there are the anniversary bundle hammers for year 2 & 3 which could easily be incorporated into trophies for 2nd and 3rd.
There was a year 1 anniversary bundle but the hammer was literally just a poorly rendered stone hammer (It was called "Classic.") We would just have to come up with a hammer for 1st, maybe something like the VIP hammer or Smash Bros.
Or we could skip hammers altogether and use Gemstones instead.
@Secret_Wonky Y'know saying "Add 4th Anniversary" means that each year, it's almost sounding like we keep adding Anniversary Hammers as time goes on (lol). (Not saying you are, but it just sounds like it)
Us Mods are talking about it as we speak. Connor hasn't looked into the icons yet, but hopefully he will soon.
But here is my opinion: I think the hammers are a good choice. I think we should take the Anniversary ones for 2nd and 3rd, but for 1st Place, I think it should be the 1 Billion Hammer.
