i would like to see something which may include some of the older races e.g. the inusannon the ones before the protheans. maybe they found a way into dark space in a place where they couldn't be detected. set after the war against the reapers in ME3, you could create a character of any of the races, depending on what you did in ME3, like the quarian choice may not be an option etc. so your actions in ME3 would matter in this game. they would start off within their own race then maybe being promoted, then brought forth in front of a unified council or newly formed senate which has members of each of the races that helped in the final battle.

you're brought forth into this new role to investigate possible threats around the galaxy, which then reveals a lone inusannon, who you find in one of the ares you are sent to search. he then reveals the plans of his people; to take back their galaxy, without mercy. he then talks about something similar to the catalyst, which was revealed in the extended cut to have been created by an intelligent race to stop chaos with 'reaper guard dogs' sort of. in which the catalyst had decided to stop chaos it had to destroy it's creators. but in this case with the inusannon they programmed this sort of catalyst to do whatever's necessary to guarentee their dominance. and with biological error, it takes it to the extreme with only a few able to escape, in which this lone one has decided to help, by learning all current knowledge in this cycle and gaining superiority, intellectually, almost like a living computer.

you then venture out with a variety of companions possibly meeting some of the characters from the first games whose species have a long enough life-spen, e.g. Liara, Wrex, Grunt etc. and they can lend aid.

something else which could be interesting is if your previous shepard, depending on whether they romanced a crew member, could involve your character being related to Shepard, like you carry their traits and have their will. this could also bring in extra dialogue with other characters, and this could only happen with a female companion e.g. ashley, liara etc. because they would be the only ones to conceive. or even just related the their companions even if they weren't romanced. it could be interesting just an idea that passed, but this could allow your characters to have even more combinations, possiblities and to make your character's more personal.

sorry for the long post but it could be interesting with so many possibilities and combinations from the previous games, where it does matter what you did before.
