In the links, you have downloads. Lots and lots of downloads. That's bad. It's annoying, cumbersome, and scares people off. What's more, folks who use multiple machines have to download the same thing time and time again, which is simply annoying. Linking to threads for the information is fine (in moderation), but forcing folks to download every little thing? No. Put the information into posts. It'll be easier on everybody.
The link should be "game info forum," not "game info thread." Minor nitpick, but rather glaring.
I suggest putting an application thread in place, as that's far more organized and manageable.
In general, the ad is rather bare. It needs some meat. while putting ethings through links is okay in general, it makes your ad look rather sparse and too many links too spread out ruins the presentation. Flesh out the group template a bit, bring in some of the information from those excessively numerous downloads, and maybe put a little more work into that prelude.
You have some docx files in the mix. Folks with older versions of MS Office won't be able to open them without a reader; another layer of annoyance with the downloads.
Constantly updating and revising documents for folks to download time and time again is about the worst
way you could possibly manage and display information for folks. Just post a list and edit the list.
The reason there are so many spoiler tags in that particular template is to keep it from becoming overwhelmingly massive after you put every conceivable bit of information inside the ad itself for ease of reference. They make an 18-page ad look like this
(though I don't expect yours to be nearly so long-winded). Linking to over half a dozen threads for information just gets cumbersome after a while compared to being able to put it all into the ad in an organized manner.
The ad is supposed to catch peoples' attention. Put all the information out front to show that you've put a lot of thought and effort into this game, that you're really going to make it awesome, rather than showing folks a skeletal ad that requires folks to go digging to find anything. You won't be able to keep their attention long enough for them to dig anything up.
