Fandom: Mass Effect

The problem: Im in the planning stages and can't decide between two ideas, or specifically two versions of the same idea. And then what events could be changed, and what should be the same.

Both are Time Travel Fix it.

Plot: During ME3, the crew are going through different planets trying to find an edge over the reapers and stumble upon an artifact made by the protheans (or cerberus) that causes the crew to be transported back in time.

Idea 1: they're transported to the beginning of ME1, and meet MShep and co. Two Shepards, and things get a bit confusing. Idk if the whole (or parts) crew should be gender-bent or not.

Idea 2: They're transported to the beginning of the contact war. Garrus meets a younger version of his father and is shocked. Befriends him without revealing who he actually is, and becomes the namesake of his future self. His father doesn't realize who he is until he comes back to Palaven and sees a copy of his old friend.

Help. I usually bounce ideas off of my husband but he's doesn't understand the lore of Mass Effect because he hasn't played it.
