Tournaments

how would the two tournaments in z have played out uninterrupted?

you talking about the World tournament saga?

goten vs trunks - trunks won
piccolo vs supreme kai - piccolo forfeited
videl vs spopovitch - videl got nearly beaten to dead.
gohan ssj2 vs kibito - gohan would have won this.
#18 vsn mighty mask(goten & trunks). even when they revealed themselves and attacked her as super saiyans. she still overpowerd them. she would have won
goku vs vegeta - goku would have won

the 25th and 28th tournaments ie. world tournament saga and end of z.

i figure that it would be goku and gohan in the final match of the 25th tournament. goku and vegeta after goku beats uub and vegeta beats mr buu.
