Hey Dr. McKay, Just wanted to say thanks a lot for your help.
Really appreciate you taking the time to look at it!

You're far more than one step away. Joining a community server is not supported and never will be, as you'd have to implement VAC which nobody has been insane enough to try.

Where are you getting a 'ready' event from? No such event exists in globaloffensive. It's connectedToGC.

It wouldn't show as in-game on the profile unless you set your persona state to Online with the setPersona() method, although that wouldn't affect connecting to the GC.
Are you still using your modifications to global offensive? Try getting rid of those, as those weren't your problem.

Set your client's persona state to Online and then check the account's Steam profile to make sure it's actually launching CS. If it doesn't appear as in-game, you're doing something else wrong.

client.gamesPlayed = [730]; // Announce we are "playing" CS2 This is your problem. The correct usage is:
client.gamesPlayed([730]);  

I'm not aware of any other requirements like you describe. Are you sure that you're logging onto Steam correctly?

No, there's no other prerequisite. Were you previously using these accounts for something like requesting item data? I've heard reports of people having their accounts "banned" from connecting to the GC after doing so.

The latest version of globaloffensive is working fine for me. Do your accounts own a CS2 license?
