There are a lot of opportunities for making games both before the main ME games and contemporary with them:


 * The Rachni Wars
 * The Krogan Rebellions
 * The Morning War
 * The First Contact War
 * The Skyllian Blitz
 * A game focusing on non-Spectre special ops contemporary with the main games. Asari commandos and salarian STG units would be fun to work with.  (Maybe even do a flip of the human integration theme of the main series plot -- have the player character be an alien in a multispecies team, and have a promising new human join at the start, similar to Shepard being made a Spectre ... only the human turns out to be a Cerberus agent who backstabs you.)

And you could weave parts of the overarching lore into them -- like dealing with Reaper artifacts that are messing things up behind the scenes. (Not to mention Reaper influence in the Rachni Wars...) Or even revive the dark energy plot, and have it solved behind the scenes. A quarian/geth themed game would be good for that one, since the geth were studying Haestrom's sun so intently.
