There really isn't much of a game to ruin... I've seen better gameplay in browser games...
-EDIT-
Sam: Digital Rights Management. You only get three activations per purchase. You need to activate the game to get access to the online content. (All the other player's creatures and such.) So if your pc crashes three times, you're screwed.
Aside from that, rumor has it that the software package they use for verifying this activation process, access to their servers etc. poses a serious risk to your computer's security, in that it opens up a backdoor that is quite easy to exploit by malevolent people/hackers.
