Srsly, I dont mean to bash the series, but the game would be more enjoyable if it were possible to lean in this thing. Not to mention that while the others are jumping and grabbing ledges (eg. like Alyx in the beginning of ep1) Gordon has to find another way round. Dont get me wrong, I like the puzzles that they have in there, but the actions that Gordon has available are a little limited. Take another game for example, FEAR, in that you could lean, melee with any weapon, and slowdown the action. None of these are evident in the HL series at all, although the slowdown part is understandable, because you would have to make up some corny thing like "This is an upgrade to your hazard suit".
