KodaichiZero. He made a slew of wonderful mods, some of which still exist today. He always lost interest in his mods after a while though, which is unfortunate. A few notable mods of his that are still around are Battle Towers, Clay Soldiers. the special creepers, brain slime, and mother spider from primative mobs, and I'm sure I'm missing one or two things. My favorite of his were the grove sprites. They were adorable little things that really help to make the world feel a bit more alive and magical. They also expand forests so you don't have to. If I could ask for one mod to be updated, it would be that one.
A sort of minion mod. Something that allows you to summon minions and buff them/heal them in battle instead of fighting yourself. That would be really neat.
We're more of a family than anything else really. Usually we just talk about whatever and generally goof off. That aspect is far more important than content creation.
