I thought you had to ring up EA to get new activations for Spore.

Thank God we live in a world, where our operating systems and computer components are perfect and they never break, because that would make the uninstall impossible... Also, thankfully, nobody needs to work and we have a lot of spare time, so we can uninstall all of our games each time we do a system reinstall...
</sarcasm>
Seriously - adding a revoke tool and pretending it's a step in a right direction is an insult on Ubisoft's part. They can take this tool and stick it up their *****. I'm not going to infect my system with malware. Once they drop this kind of DRM nonsense I might try out their game. Until then, well... There are other publishers, more worthy of my money.

All right now: If you uninstall the game correctly, you'll have one of your installations back. Meaning you can install it on 3 different computers, obviously even for multiplayer... I'm not saying that's good, I just think it might change someone's mind about buying it

As far as I know, they only increased the number of installations you're allowed to perform from 3 to 5, they don't have the revoke tool as in Far Cry 2. So are you sure, you got a link perhaps?

Looks like I'm not buying it. I refuse to pay for a rental service.

Where can one download cracks for the latest games? Wouldn't that solve the DRM problem?

It would certainly fix the game itself - it would work without any restrictions. Sad news is: SecuROM would still be installed during the game setup. And that means malware on your machine.

Is SecuROM installed with the game files itself or is there a separate installer that comes after the game is installed?

It's installed automatically during the game install, and not uninstalled when you uninstall the game. Unless of course FC2 use a completely different version that behave differently than the older one.

Cracks it is then. :)

I'd hardly call illegal measures a proper solution, and circumventing copy protection does happen to be illegal. Despite that you supposedly have the right to make one backup copy for your personal use. (And that's not even mentioning the instances of DRM disallowing you to play a game you actually own.)
Fun thing being that happens without you even being notified about it, most of the time.

Installing anything - malware in particular - on YOUR computer without your knowledge or consent also happen to be illegal - that's why EA is facing two nasty law suits right now.

Sorry, but I barely noticed the Spore DRM...5 PCs is a lot of machines. Also, its hardly securom.

It's total 5 activations on up to 3 machines, not 5 machines.
Many people have more than one machine. I personally install my games on two of my three rigs (and I'm the only one that lays them). One of them is not connected to the internet. As well, others also have laptops (all of my machines are desktops).
Also, try upgrading your rig, changing your BIOS settings, reinstalling your OS, or (sometimes) just upgrading your drivers and see how long it takes before you notice the DRM.
Not sure what you mean here exactly, but it's completely and totally SecuROM.
