ZehDon's totally right about "gamer" being hardly more precise a category than "reader" or "grain-eater." For TBS lovers, this thread needs more 'epic' titles (and no, Star Wars doesn't count after the first two films; George Lucas let perhaps millions of us down with his descent into blockbusterdom).
A version of Starship Troopers done by someone who loves Heinlein as much as Peter Jackson loves Tolkien would be awesome. Even better would be to see someone give a good try at The Moon Is a Harsh Mistress or Time Enough for Love. Lazarus Long is definitely an epic character whose life often seemed like a horrible and/or wonderful game.
The two miniseries Dune (2000) and Children of Dune (2003) cover Frank Herbert's orignal Dune trilogy, and the first part is far superior to David Lynch's theatrical attempt from 1984 (and I say that as someone who really loves some of Lynch's other work). You can rent them, not sure if the DVDs are still available at retail.
Edit: SpardaSon, thanks very much for the tvtropes.org link. I'm a non-recovering postmodernist, so it's great fun to see people define and whine about something like 'popcultural osmosis.'
