Honestly, I'm still really on the fence if I want another Mass Effect to take place in the future, for the fact that it creates a canon ending, which isn't a big deal, but personally I would prefer the ending where the Reapers win to be canon. Then we see a society who gets Shepard beacons and is fully ready for the Reapers or have already stopped them. Then it is a trilogy more rife galactic politics, war between species, new world contacts. It could be more in-depth as far as how life would be. There's more to that thought, but I will go into it another day.

One set in the "past" might be cool. Something that chronicles the biggest war events. Rachni war, krogan rebellions, First Contact War, etc. Play a military academy cadet and participate in actual battles (holographically of course). I imagine it similar to the beginning of FFVIII with the SeeD trials and the written SeeD tests accessible throughout.

Though honestly, I'm not sure if I want to revisit the universe. I love Mass Effect, but is there any reason to visit the past, explore the possible future, or have concurrent side stories? The last one might work, different species, etc. Playing as some of the major players or random things. Play some of Aria's life story, early life of Mordin, a mission as an agent of the Shadow Broker (perhaps Tela Vasir?), life as the greatest former Spectre agent Saren, maybe doing a mission with Nihilus?

I'm just sort of rambling though.
