We're of the firm opinion that your time is too precious, too valuable to be spent reading a full review for a game that was already reviewed many, many years ago. What's the point of applying a score to a game that's old enough to be enrolled in the sixth grade? That's why we invented Deja Review: A quick look at the new features and relative agelessness of remade, revived and re-released games.
Quarrel was originally planned for XBLA, and then all the publishing deals fell through. Then Ignition took it on and began working with developer Denki on an iOS release -- which ended up coming out first. That makes this XBLA version, which was the original version, a re-release. Weird!
What isn't weird is playing this on XBLA. It's still just as difficult to battle over territory by quickly spelling out anagrams, and just as satisfying to capture your opponent's soldiers by doing so. The combination of fairly quick board-game design and online play is an obvious winner, giving it a decisive advantage over its portable counterpart. Even if you're playing alone, new modes offer experiences not found in the iOS release.
