What game series should come out only once every videogame generation?

I agree with Mario Party.

Final Fantasy should be only 1 per generation.

 

That will most likely be the case if you are just talking about the main series

 

Maybe this generation, but previously the first ones in a generaton were the best, and started slipping. See FF11 and FF12 compared to FF10

FFXI was shunned but FFXII was better.  Even so, FFX will always be the best FF of the 6th gen
