The similarities to Ender's Game are rather striking. So much so that the parallel might be a little belabored at this point: I've noticed a number of reviews saying that they'd like to see less of the "Quirrell's Armies" business at this point, and I tend to agree.
I do agree that the "deep game," if by that you mean trying to suss out Quirrell's and Dumbledore's ulterior strategies and motivations, is quite fun.
I dunno, I liked Ender's Game, and I would have liked it better if it had been written by the Wise Master instead of a crazy person. The Houkago Wartime parts aren't my favorite parts of the Methods, but I sort of suspect that they are not in competition with the parts that are - I suspect they are easier to write than the more mainstream plotty parts, and so they may well act to help the story keep being written, by giving the Wise Master a relatively easy, unintimidating place to start writing.
Update: Discussion has moved on to a new thread.
The load more comments links are getting annoying (at least if you're not logged in), so it's time for a new Harry Potter and the Methods of Rationality discussion thread. We're also approaching the traditional 500-comment mark, but I think that hidden comments provide more appropriate joints to carve these threads at. So as of chapter 67, this is the place to share your thoughts about Eliezer Yudkowsky's Harry Potter fanfic.
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: one, two, three, four, five, six. The fanfiction.net author page is the central author-controlled HPMOR clearinghouse with links to the RSS feed, pdf version, TV Tropes pages, fan art, and more, and AdeleneDawner has kept an archive of Author's Notes.
As a reminder, it's often useful to start your comment by indicating which chapter you are commenting on.
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
