Here's an excerpt that should do a better job at describing all of it:
Expert Mode will disable all of the common ease-of-use / in-case-you-missed it gameplay elements like the display of skill thresholds, influence/reputation modifiers, and similar "helper" information. In a fashion similar to Fallout: New Vegas' Hardcore Mode, Expert Mode will also enable more punitive and demanding gameplay elements, in and out of combat. We're not saying we're going to have weighty gold (for real, we're not saying that), but if we did, you can bet that would be automatically turned on by Expert Mode.
If you guessed that Trial of Iron is like Temple of Elemental Evil's Ironman Mode, you guessed right. When you start a Trial of Iron game, you have one save game that persists for the entire campaign... or until you die. And if you die, your save game is deleted. Enjoy!
Path of the Damned is a spiritual successor to Icewind Dale's Heart of Fury mode. In our encounters, we like to turn individual combatants on and off based on the level of difficulty. If you come into an area on Easy, maybe casters are replaced with weak melee enemies. If you come in on Hard, maybe the casters are augmented by a tough melee enemy or two. With Path of the Damned, that goes out the window. All enemies from all levels of difficulty are enabled and the combat mechanics are amplified to make battles much more brutal for everyone involved.
The first question you may have is, "Can I enable multiple challenge modes at once?" Yep, you sure can. They have to be selected at the beginning of the game, but if you want to play with two or all three at the same time, you can certainly can do so. If you're not quite sure you want all of the elements that come along with a given mode, this funding level will also cover implementing the ability to enable and disable the individual sub-features.
Along with these modes, we also want to introduce the Godlike races. These folks have been described previously as being similar to the humanoid "planetouched" in D&D: aasimar, tieflings, and genasi. That is a good high-level description of them, but they are viewed differently by various factions, faiths, and cultures in the world of Project Eternity. Godlike were "blessed" before birth by one or more of the meddling deities of this world. Though their appearances vary, they are unmistakeably otherworldly when anyone gets a clear look at them. Sometimes, the reaction they get is overwhelmingly positive. Many times, the reaction is overwhelmingly not. For better or worse, the physical "gifts" that mark them as Godlike always come with supernatural blessings (and curses) of their own.
By the way, you might have noticed already that Project Eternity has currently reached (and exceeded) its $2 million stretch goal, which means the game will also include a player house among other things.
