Is there a point to system link anymore?

System link used to be THE thing when the original Xbox came out.  You can have massive games with friends all while in the same house.  Then came tunneling software like XBC and Gamespy, where you can play people across the world, especially in titles like Halo.  But with the advent of Xbox Live, the way of system linking kinda went the way of VHS.  Why would I need to drag my Xbox all the way to a friends house, when I can just link up on Xbox Live.

The benefits of Live are pretty big.  I can be playing any Xbox Live game, and receive an invite to play another.  If I am on Guitar Hero 3 and my friend wants to get some Valentine's Day playlists done on H3, then he can shoot me an invite, I accept it and all I have to do then is put in and launch Halo 3.  Very simple, right?  Exactly.  There is also voice support, so we don't need to scream for everyone to join or setup, etc...

BUT!  To my dismay last night, I found out that while Call of Duty 4 can do system link it is COMPLETELY useless.  I can understand the 1 person limit in a Xbox Live match, but...for system link?!?  It was a huge disappointment and makes me wonder why the heck a developer includes it for that.  It is truly worthless at that point.

Well...we played Halo 3 instead.
