Meaning you need to check if A is more than 10 bigger than B AND if A is more than 10 smaller than B, correct?. So...

That will not list values in B which are at least 10 bigger than A; it will only list values in B which are at least 10 less than A!

Thus the correct clause would then be:
sql code:
...
WHERE (
    ABS(A.playerupgrade1 - B.playerupgrade1) > 10
    OR ABS(A.playerupgrade2 - B.playerupgrade2) > 10
    OR ABS(A.playerupgrade3 - B.playerupgrade3) > 10
    OR ABS(A.playerupgrade4 - B.playerupgrade4) > 10
)
ABS() = take the absolute value of the number

Ah... In that case I never said anything ;)
