I'll just copy and paste, then change things around to see what happens. Editorial interjections will be in [brackets].
Getting Started
You have been chosen to compete in the Arenas of Rokkur in a contest against your rivals to ascend from the mortal places into the Pantheon of the Gods. You shall battle both alone and on teams of convenience with and against your fellow Demigods. These Demigods have come from different realms, different worlds, and different planes of existence to win the favor of the Ancients [when the gods are mentioned directly I prefer to be consistent and use Ancients] and ascend to Godhood.
Each victory in an arena provides you with favor points that you can use to move closer to ascension, drive an opponent further from ascension, or acquire special items to aid you in future battles.
Installation & Updating
Installation requires approximately 3 gigabytes of disk space on your hard disk drive. After running the game for the first time, press the “Update” button from the main menu to make sure you have the latest version of the game.
The update button will open Impulse, which will require you to create an Impulse account if you don’t already have one. A valid email is required to make an account. This account will be used if you play the game on-line. Impulse will allow you to update to the latest version as well as to re-download the entire game should you lose the DVD in the future. It will also allow you to play the game without the DVD. You will need your game’s DVD key to register the game to your Impulse account.
The Arena
The Arenas of Rokkur do not exist in the mortal realm. They are a manifestation of the will of the Ancients with the sole purpose of helping to prove which Demigod is the most worthy to ascend. This means that while Demigods can die in Rokkur, it is not a permanent death so long as it occurs within the arena. Similarly, the arms [this refers both to armor and weapons, so I think it works better than either one, especially if no actual weapons are included at release but some are added later, or something similar happens], items, and other tangible constructs only exist within the Arena in spiritual form. Thus, Demigods [the part about those who recognize that fact seems unnecessary, especially since the manual comes right out and explains everything] can stack different types of items together in ways that could not be in the mortal world (it also means that these items, when equipped, cannot be seen [visually seen is redundant] by observers or other Demigods).
Anatomy of an Arena
Each Arena is made up of several key elements:
1. The Great Citadel. This is the base of your side’s power. If it is destroyed, your side loses. You can use gold [perhaps make a quick mention of ways to earn gold, though it might be best left for later in the manual] to upgrade the Citadel. Citadel upgrades can increase the frequency of reinforcement waves, the power of those reinforcements, the strength of your team's fortifications, and other such things [it seems like it might be good to explain why upgrading is worth bothering with].
2. The Item Shop. Arms, potions, and other items are purchased at the Item Shop [consistent capitalization of terms].
3. The flags. Scattered across the arena are several different kinds of flags. Controlling flags is very important [because I can imagine a scenario where the team that does not capture any flags could still win, I think saying "absolutely crucial" is a bit too strong] to victory. Control of flags earns your team war points which provide access to better types of reinforcements, upgrades and more. The types of flags are:
a. Flag of Experience. Controlling this flag will result in your team gaining experience at a substantially greater rate.
b. Flag of Celerity. Controlling this flag will result in spells having much shorter cool-down times for your team.
c. Flag of Brilliance. Controlling this flag greatly increases the mana pool for all Demidgods on your team.
d. Flag of Fortitude. Controlling this flag greatly increases the hit points for all Demigods on your team.
e. Flag of Valor. Controlling this flag greatly increases the strength of your reinforcements (hit points, attack, defense, etc.).
4. Special Structures. There are several special structures available in the arenas. When captured, they can provide more reinforcements, more gold, access to artifacts, and more.
The Types of Contests
The Ancients have arranged a variety contests to take place in the arena. In all cases, destroying the opponent’s Citadel will win the game regardless of other victory conditions. The types of contests are:
· Conquest. Destroy the enemy’s Citadel to win.
· Dominate. Control the flags for a certain amount of time for victory.
· Slaughter. Attain victory by killing a set number of enemy Demigods.
· Fortress. Destroy your opponent’s fortresses to attain victory.
· Protect. Keep your opponents from taking and escaping with your War Idol back to their Citadel.
*a note about lists: when making a list I find it works best to include commas for all parts, entries, items, etc. This eliminates confusion in certain circumstances. For instance, a list of words and phrases describing extra things you can get might include bling, flash, and bells and whistles. Without the last comma, it'd look like bling, flash and bells and whistles, which is confusing. I suspect a lot of English Major types were taught to make lists without the comma though, so it's really up to you guys which way you want to go.
