@Losey are you able to do this?
To the first issue: Can you post the contents of the game.xml for Full Spectrum Warrior (2004)? You're folder structure seems solid so that shouldn't be the issue, curious why that one game is populating under another platform.
To the second: Didn't the gamesdb API change a while back? I thought I read that somewhere on the forums, I don't currently have GB setup so I can't test it. But if so that might be the issue. I don't have a day off until next weekend but I can set GB up to check it then.
To the third: I'm not sure on that one, im not certain on how emby marks items for watched status.
Apologies, busy month and I forgot to check back in. Here's the contents of the "Full Spectrum Warrior (2004).xml" file:

<Overview><![CDATA[In Full Spectrum Warrior, you take on the role of commander of two squads of the United States military, Alpha and Bravo, as you guide them in the fictional country of Zekistan on a mission to capture or kill the terrorist Al Afad.
In the game, you don't directly control your troops. You don't take aim at a target and shoot, and you don't circle-strafe around enemies. Instead, you tell your squad what to do, and they'll do it. It's like a real-time strategy game. You can tell your two squads to do numerous things, such as hide behind a wall, take cover behind a car, lob a grenade, fire off a rocket, or attack a target. You will need to utilize both squads to be successful. For example, you can have Alpha squad hide behind a car and lay down covering fire at a target that you can't directly kill, giving Bravo squad cover so they may cross open terrain, and get into a position where they will be able to kill the enemy.
The game takes place in one locations, a Middle Eastern country, that's split up into several areas. You'll have to make your way through parks, an airport, city streets, and even some buildings. Throughout the country are many terrorists, all of whom are trying to kill you. You have four members on each squad; the Team Leader, Automatic Rifleman, Grenadier and Rifleman. Each plays a unique role.
Full Spectrum Warrior supports Xbox Live, where two players can play through the single player campaign. Instead of controlling both squads, one player controls Alpha while the other controls Bravo.]]></Overview>
