all games are not created equal

Based on the fact that many people rave about Perfect Dark, I am well prepared for the counter-argument. 

My basis for this comparison revolves around the multiplayer aspect of 007.  Both games single-player scenarios are great and I simply cannot say that one is better.  However, 007 offers, for the first time a chance for a group of 4 to run around killing one another.  It not only was the first but it also setup a framework for how games should do it in the future. 

Perfect dark of course followed this frame work, but really didn't improve on it.  Sure the weapons were cool, but the levels were no match.  (To this day I still think the Complex is the best battleground made).  Perfect dark broadened the scope of options, but failed to take any deeper.

Ultimately, if I had 3 other friends sitting in the room, I'd much rather play 007 than perfect dark, maybe for the shear nastalgia, and that in itself is justification.

Perfect Dark innovated about a hundred times more than the Halo franchise ever did. Perfect Dark has dual-wielding of the same weapon, Halo has no dual-wielding. Perfect Dark has alternate modes for every weapon, some quite different from the main function, and Halo does not. Perfect Dark has many more unique and fun weapons, Halo has very few weapons. Perfect Dark has amazing in-game music, Halo only has a decent main theme. Perfect Dark has a fun, replayable solo campaign, Halo has the Library. Perfect Dark has Co-Op and Counter-Op two-player modes, Halo only has Co-Op. Perfect Dark has many more options for multiplayer such as customizable avatars and bots and fun levels, Halo has palette swaps and Blood Gulch. I still play Perfect Dark with my brother, and Halo sits in a stack gathering dust.

The only advantage Halo has is system link for up to 16 players, which is indeed amazingly fun.
