Will GameTracker list servers for games like:

Battlefield 1
Call of Duty: Modern Warfare 2
Call of Duty: Advanced Warfare
Call of Duty: Infinite Warfare
Call of Duty: Ghosts
Call of Duty: Black Ops 2

?

Am curious why some of these games are not listed.

I think it's due to these newer games like Battlefield 1 doesn't want to release their dedicated server files to the public, maybe due to the fear of getting their server files cracked by the pirates and not moving into newer games when they decide to pull the plug. Even if someone manage to crack it, their game server engine and advanced physics require massive server hardware requirements to operate, which EA asks like $600 per year from anyone that's willing to buy one of their dedicated game servers. Their business practices make their game mostly anti-piratable, in other words all of their servers are indeed legit and official which they can list in the game client without even thinking about it.

Since I don't even have a chance of running a game like Battlefield 1, a simple google search shows that they don't allow users to view the actual server IP addresses. But I might be wrong so I would let someone actually played the game to confirm that. No server IP addresses, No public server query API to properly extract server information makes it almost impossible for a game server listing like this to add support.

Most of those other games that you listed have all or some of those issues above. So the basic idea here is that, most newer games actually want to maintain their server lists in-game or in one of their own official listing. Don't know if this concept gonna take over in the future, it most probably will as far as it seems.

This sufficiently summarizes possible issues;

Reasons we may not be able to add a game:

1. The game is not sufficiently popular.
2. The game uses a custom query protocol that we are not able to support.
3. The game does not have query support.
4. The game does not have dedicated servers.
