Ripping the idea straight from LOTRO. Have a taxidermy vendor that take special drops I find on animals throughout the world that I can then trade for a trophy of that animal to place in my house. I loved having my giant standing taxidermy bear greeting folks in my LOTRO house and having my walls cover with fish caught. Hell... take the fish here a step further and allow the trophy to show the stats so fisherpeople can hang their most gigantic catches as proof of their accomplishments!
