unrivaled : adjective
eminent beyond or above comparison; "matchless beauty";
unparalleled: adjective
radically distinctive and without equal;
So with 'unrivaled' you cannot even compare it to other games and with 'unparalleled' you simply do not have an equal, upon which someone could then add the word "YET" so I say unrivaled would be preferred if you do not want someone adding a caviat in the press.
(and yes using 2 L's is British spelling)
Fair enough. I still think "unparalleled" is the better term however. This is especially so given the marketing angle being pursued by SD and IG.
Additionally, I asked my nieces and nephews (8 to 22) as well as some of their friends which word they liked more. Nearly all of them had more of an affinity for "unparalleled". I also asked my step son and his friends as well with nearly the same results. It should be noted that he and his friends are not native English speakers. Additionally the middle school level kids clearly understood the meaning since they learned about such things in geometry class. The exception was the native English speaker high school kids. They liked "unrivaled" more because they thought of school sports teams and their "arch rivals".
Regarding your caveat statement, you know there will be cheeky comments about the misspelling on the box by kids and maybe media in the US dont you?
