I'd send a ticket and ask them regardless.

I attached a screenshot of the welcome screen to Tales of Maj'eyal. I was a little sloppy with my testing process. It went as follows:

1/ Install game
2/ Register account and use code - doh!
3/ Check add-ons and notice the following: ToME add-ons dev tools, Items Vault and Stone Wardens bonus class.
4/ Realise that I hadn't checked the game WITHOUT the code. Uninstall(including save data), reinstall, don't log in and the add-on screen shows the identical thing with a reinstallation and me not logging in.

I haven't checked the difference with patch installed but was surprised to see the same 3 items in my add-on section with a reinstall and not being logged in. Registry change leftover perhaps?

I already did that. I just asked publicly to see whether someone else had an experience to share. Oh well, I can wait.

According to Judas, the code can be used for achievements. In addition, frimbri has listed a number of features that require the usage of the code.

Thanks for the extra info. Re Spellforce 1&2. I thought I'd take a look at see what the Steam versions were like and they are listed as single-player only. Did Nordic strip all multi-player features?

The penultimate Internet Wayback Machine backup for SpellForce Platinum (because the last one doesn't work properly) mentions this tidbit:

"The game's multiplayer servers have been taken offline and the only option available is LAN. To get your unique, multiplayer CD-key, please see this support article."
If you are interested in trying it out, here is a guide for the game.

Thank you, i guess if i ever want to play it online i'll just use hamachi to simulate a lan game and be done with it.

My time machine is buggered and keeps hurtling me forward through time at the alarming rate of 60 second per minute! I was just reading the Spellforce forums re LAN play, and the thread mentioned needing a unique key for it. I wonder how that works? If I was remotely interested in multi-player gaming, I'd pursue it.

I guess in a way similar to Neverwinter Nights, which checks for your key even for LAN.

NWN and NWN2 both require serial numbers. The game actually uses your CD key to identify who you are in the game. It also gives server admins more tools -- for instance, they can blacklist your CD key or only allow a certain CD-key to access the DM-client (giving further security for a server).

You don't have to do a LAN with himachi (I don't recommend using Himachi anymore for any games -- it installs stuff on your system that will render some games completely inoperable with LANs (I think IL-2 might be like that, but I can't remember). I've been using Teamviewer's VPN flawlessly.

Nonetheless, you can direct connect by just entering an ip address. If you have one of those wonky big IP addresses, just google "What is my IP address" and use that.

To start a game, just start a new module under multiplayer and then people can join. Or, better yet, use the stand-alone server program that will make a server that you can play on. (nwserver.exe for NWN 1 -- I don't have 2 installed right now)

By getting your unique serial number, you can have 2 people play on NWN1 (one with the default, one with the new ID). With NWN2, you need 1 game per player.

It's DRM. It's not removable DRM. But it's DRM built into the foundation of the game. It sucks, but it's got its uses, too.

Thank you for the information, i'll bookmark it if i ever need it to play online (doubt it but still).

Bump. If you can find more games with a serial number that are not on the first post, make sure to mention them.

Added Two Worlds to the list. Waited a bit before doing so, as I wanted to confirm it myself, but credit should be given where credit is due. Thanks!

Another bump. If you can confirm any of the unconfirmed games, say so. If you also have one of the new games that might be coming with a serial, but is not listed, mention it.

Thus, the biggest question looms its head; what bonuses does registration provide that you can't get with the offline version? Is frimbri's post correct?

Hey Judas, how long will PixelJunk be on sale?

(Since you happened to drop by on your day off...)
