I was feeling nostalgic last week so I started playing Unreal again.  Probably for my third time through at this point!  While Unreal doesn't have as much replay value as a game like Half Life it certainly does have its moments!  Unreal was one of those really impressive FPS games for it's time.  It boasted great graphics and intense game play.  Of course by 2008's standards these graphics merely look silly!  But if you were picking this up in '98 like I was, you were pretty impressed.
