I'm sort of surprised that they haven't in the run up to Andromeda (like Uncharted did) actually. Although it would be hard to make a cohesive trilogy set IMO because of how differently ME1 plays compared to 2 and 3. My biggest gripe was that my FemShep was a biotic and by the end of ME1 her biotic powers were through the roof... she could basically nuke entire groups of enemies... but then in ME2 biotics were toned down massively. And also the flimsy explanation for why you need ammo in ME2 and 3 when you didn't in ME1 :joker:.
