Mass Effect 5 would have let players generate alternate timelines based on their choices in previous games, according to the series' technical director

The more information that dribbles out from BioWare's cancelled Mass Effect game, the sadder I feel about the whole sorry situation. We've already seen an in-engine trailer that introduced a new protagonist and reintroduced Liara T'Soni, and we've heard that the game was set in a 'galactic Cold War' that combined all three of Mass Effect 3 's possible endings. Now, it seems the new Mass Effect would also have had a sophisticated system for dealing with the choices players made in the original trilogy.
