Hello vizzed as some of you may or may not know I am starting a YouTube channel, it’s actually launching this Wednesday on January 24th on 3:30 pm pacific time, and my channel is a discussion channel about video games Star Wars and dragon ball Z. I am currently working on scripts and I can’t decide which idea I should work on first for my dragon ball what If videos and I would really appreciate your input. Thank you all in advance for the help (this was supposed to be a poll I’m not sure what happened? But any way I’ll just list them and read the comments I guess) (can someone explain to me what happened?)1. What if Cell survived his fight with Gohan (bring an improved cell into super)2. What if Broly defeated the Z warriors (Broly Vs. Buu)3. What if the Sayains believed Bardock about Freeza4.What if Future Trunks came back during the Buu saga5. What if Gohan died in the Sayain saga (goku goes super Sayain early)6. What if Future Gohan came back instead of Future Trunks 7. Any idea you have that you think would be more interesting than any of the above that you would be okay with me possibly using as a video on my channel.

I think numbers 1 and 2 are the most interesting ideas. My favorite would be number 1. 
I can't think of anything to add to your list. But if I do I will come back and comment. I think the channel is a great idea. I love DBZ!

@Kilian: my channel is live now at Unpro Gamer on YouTube the first dragon ball video will be up either Friday or Monday 

I think seeing the outcome of Gohan dying would be the most interesting path to take.  It also depends on how well you write, develop story lines, and how creative you are.

Write that.  For me, a character dying off is always a good thing because it forces changes in the plot and the story and we're forced to deal with something we probably never expected to come.
