We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
I haven't played in like 8 months, and even 8 months ago, there were not many people playing. I'm not sure if there are still people who play Colonies, now that Lost Planet 2 is out, but you could always try.
