If Future Gohan didn't die, how do things change?

[Warmmedown]

1. Trunks grows up and fights the androids together with Gohan. Do they hace a chance by then, having trained together? Did Future Trunks even have training partners? He never mentioned anybody and we never saw anyone in the manga, TV Special and I'm guessing not in Super or GT?

2. Trunks comes to the main timeline, but so does Future Gohan. How does it affect the combat against the androids? Do 17 and 18 even get revived? Does Cell get to Perfect?

I don’t think that helps, otherwise Gohan killing himself is pointless.

Androids Saga, everything goes the same. Trunks was useless af and Gohan will be just as useless. He’ll probably take Kid Gohan’s place in the Rosat with Goku though, so Future Gohan vs Cell might be interesting.

It was pointless, in the sense that if he'd survived Trunks could achieve ssj another way and then they fight together. I don't think he had to die for Trunks to eventually achieve ssj.

For 2. Wouldn't Gohan have powered up? He was already quite strong when he died, and then he and Trunks would train together and get stronger.
When they were trying to stop Gero waking up 18 and 17, an extra saiyan could've prevented Gero doing it. Did Vegeta let Gero get away? Gohan wouldn't.
And then if they don't prevent 18 and 17's revival in the rosat, maybe Future Gohan trains with Piccolo. Or with Future Trunks. The two person limit is an issue. If Gohan can power up in there, he and Trunks could stop Cell frok becoming Perfect. Trunks can keep Vegeta at bay, Gohan kills Cell. But the two person rosat limit is the issue.

Bulma builds another space pod for Future Gohan and Future Trunks to go to New Namek instead of building a time machine.
