Hmm new blocks and ores...cant go wrong with something like Mithril, Titanium, Platinum, Truesilver, Fools gold, Blood Diamond blocks, Dirt blocks that dont grow grass maybe? (Kinda like mud). PEARL...which was mentioned by my brother in-law. Ivory and maybe Desert Grass (Savannah grass whatever its called). Wood panels with different wood patterns would be nice. Chest that are like iron metal rusted silver gold...Just some ideas.
