Well i was just thinking this: Perhaps each player could choose his own sigil? Or even create one(like in some games, halo 2 for example)? The sigil could go on your armor, banners(if you place any in your house), door(if you want to) and so on. I know it's not a very large thing, but still, it would add some additional customization. And you could put your mark where you go(for example when you discover a new planet(/moon) you could raise a flag with your symbol on it). It could have other uses too.
Sigil makes it sound all magical and mystical @__@ I do love the idea of having your own little symbol/logo, mostly because I'd love to just leave my mark places xD
I think this would make for a very interesting addition to the game. When I first saw this, I though of the unique sigils in the game Journey.
I WOULD LOVE THIS!!!!! no really, i would love to plant my flag on a creeper's foot and declare this land for my own *B00M*
anything that adds more customization I am usually in favor of. This sounds nice, I would like an option to make a symbol/logo/sigil because if I put it on my armor and everything it makes me sound proud and boastful.
