Games:

   ADOM (Thomas Biskup):   A nice Roguelike, though the fixed plot elements eventually grate on some.

   Dungeon Crawl (a "DevTeam"):   Another worthwhile Roguelike.

   Nethack (a "DevTeam"):  Threetoe's favorite.

   T.O.M.E. (Dark God):   Described to me as "sooo munchkin", it has many features beyond the original Angband.

   SAngband (various):   Interesting Angband variant (a bit buggy last time ToadyOne played it).

   Tom Proudfoot's Games:  some entertaining games here - and message boards.

Unrelated unless you're really creative:

   Iggy Pop:  Still going.

   News Hour with Jim Lehrer:  Tom Oliphant knows he's mischievious.
