The ending provided very little in the way of closure, setting up a number of plot points for a sequel that has never arrived.  >With the exception of 2011’s Portal 2, the Half Life universe has remained completely dormant for almost ten years, which is a shame when Half-Life and Half-Life 2 are generally considered to be two of the best games every made.
