-I'll focus on the underlined text, since you seem to take an approach of read at least that:

totally replace all of your video games, all of your MMPORGs, all of your old D&D books (yeah, I know you still have them!) and even your Magic cards?

What totally replace all my..? Start from the beginning. a gaming experience that would totally.. So, a gaming experience should be underlined too.

you can experience it all for FREE, at no risk or obligation to you. You will never, EVER give us a credit card, and no money will EVER exchange hands.

No money will ever exchange hands? What's that donations button in the sidebar again? The statement is a lie and you know it. The game does accept money in the form of donations and there are people who do donate to the game. That's money changing hands. You'll need to change the wording to be truthful so that people can trust what you say. Otherwise they'll think it is all lies. Honest truth is our best selling card here, as there's plenty of Free* and Free(1) games out there who market with lies or by omitting the uncomfortable parts.

-The love of white space. Put line breaks between the items in the list. The underlining of the beginning was a good thought, but the line breaks will help to see the text blocks separately so that people will bother to read them.

-The game may be text-based, but you need artwork to give that imagination something to start on in visualizing the world and getting people interested in it. Immortals, landscape, etc. The welcome page needs to have at least one picture of artwork illustrating Thera.
