Halo is simply utter CRAP when compared to Marathon's deep storyline, excelent puzzles and wonderful shoot em' up 2.5D gameplay. I tried Halo demo on the Mac and it's just as boring as any Quake out there.
The problem is that the kids nowadays only see graphics and FPS. Marathon was WAY more than that, at a time when Doom, another piece of crap, dominated the PC scene.
I can only remember a great many hours spent on my Quadra 605 with Marathon I and II...simply wonderful games. If they could only develop Marathon 4 with similar originality, I would be happy.
I agree with you! What is the deal with Halo, I think it's identical to Doom 3 or Unreal 4. Just a booooooring shoot em uper.
