Being in Australia, I have just purchased UFO from Gamersgate and I am downloading now. So far, there does not appear to be serial number (at least no serial is listed) and the game was $10 cheaper (US$29.95) than the Matrix version I think, although I would still have preferred to purchase from Matrix (becasue I like to support the company).
I can't comment yet on the requirement for an Internet connection although their general FAQ indicates that one is required. I have purchased Take Command: 2nd Manasas from them previously which did NOT have a serial number and does NOT require an Internet connection to install or run so it looks like they do change this on game by game basis. I have installed Take Command with and without Internet connections many times so it looks like that game has no install limit.
They also inidcate that there limited install policy is only for multiple installs over a specified period, not for the life of the game. What I think that means is if the game is installed many times in a short period of time, say one or two weeks (only guessing at this), although the total number of installs is not limited. If you at the series of questions below, you should see what I mean:
Q: Can I install the games on my Laptop as well?
A: You can install the games on any of your computers as long as that computer has an internet connection.
Q: Will I be able to install the game on my new computer once I upgrade my hardware?
A: Yes, the game stays available online through your GamersGate account.
Q: Do I need an Internet connection in order to play the game?
A: No. An internet connection is only needed during the installation process and the first time you run the game. After that no more internet connection is required.
Q: I have re-downloaded the game and it does not install anymore. What can I do?
A: In order to prevent fraud and account sharing we monitor the number of installations made per account. If your account/game has been locked due to a high number of installs within a period of time please get in touch with us at
There is no mention of limiting the "total" number of installs, only the number installs during a "specified period". That could mean if the game is installed 10 times in a week for example you may have trouble, but if you install it once a month for two years you won't. This is just my interpretation of their FAQ, I could be very wrong, but my experience with Take Command makes me believe this is the case.
I will report back on the Gamergate requirements when I have it installed. I will attempt to install and run it with my Internet disconnected to see if it is actually required or not. If it is not required then the limited number of installs is a false alarm.
