It appears that Electronic Arts editing their wiki's history has been one-upped. MaxConsole is reporting that Sony Computer Entertainment Europe was caught red handed editing the Halo Wikipedia entry by adding in the line "Although it wont look any better than Halo 2."
And of course, the changes can be viewed thanks to the revision history, but the page has been locked to bar further tampering. Funny? Sad? I'm really not sure what to think of this, to be completely honest.
