Although the destruction of Normandy 1 occurs in the first five minutes of Mass Effect 2, Bioware rightly tried their best to keep the segment under wraps. For those who have played the first game, the reveal is powerful. In the scene, an enemy vessel carves into Commander Shepard's ship, ripping it apart. She ensures her crew's safety, walking through zero-g carnage to reach Joker, her ace pilot. More than establishing a fast-paced tonally dramatic introduction, Mass Effect 2 quickly establishes its intent to evoke nostalgia for the game's first iteration. By stressing the importance of the first game within the world and its characters, Bioware elicits sentimentality with an unprecedented success.

Alternatively, complete consistency between two games merely elongates one experience without evoking any sense of nostalgia. The Halo, God of War, and Gears of War franchises iterate slightly between each title, mostly maintaining one narrative arc and mechanical experience across multiple games. While a few twists remind the player of past narrative events, the games stand largely as one whole. Mass Effect 2 maneuvers between these two limitations, inconsistency and regularity, by demarcating the relationship between the two games with an obvious metaphor - the demolition and reconstruction of the Normandy.

Commander's Shepard's interactions with old crew members and early dialogue options also develop nostalgia for past experiences. When first regaining consciousness, Shepard may inquire about the status of her past team members. When talking to Lt. Anderson and Joker, she may also probe further into the whereabouts of her old friends. While they have all moved on, no one reoccurring character is unaffected by their past. Garrus, Joker, Anderson and others express longing for the halcyon days working for the Alliance. Even Doctor Chakwas, a relatively insignificant NPC from the first Mass Effect, joins Shepard's crew. If selected, Shepard joins the doctor for a drink, reminiscing about bygone days and their shared memories.

For those unable to import ME1 profiles into ME2, the experience could be very different. The mechanical and interface alterations may not evoke sentimentality from any player, but perhaps the scatted sci-fi references dotted around ME2 may serve to evoke nostalgia - in this case, for Firefly and Star Trek. Regardless, Shepard's consistent concern for past crew members, her numerous dialogue options that encourage reminiscence, and her encounters with old friends, should resonate with new and old players alike. Bioware succeeds in evoking sentimentality by doing what so many games have failed to do: making the first game clearly meaningful to the protagonist and her compatriots. It is a form of expert world-building few developers have even approached and Bioware should be lauded for it appropriately.
