It is interesting that despite being totally wrong when you made that joke about FFX, and me correcting you, that you were bold enough to make the same joke about VII's. Admittedly in that case you were correct.

In VIII the stats are linked to the GF, and lay a heavy basis on which characters were equipped with which GF. Given there are only very slight differences in the actual summon command with the exception of X it seems logical to delve further. This has been done with other FF's than VIII.

On that note I'll repeat that if you criticise VIII for repeat summons (which I've already justified) then at least mention X which does the same thing, but makes the whole thing much, much easier. I also believe that in X summon sequences can be sped up, and I know that you don't lose SeeD levels, leaving it with no disadvantages at all in comparison to VIII.
