Like Garrus Vakarian, Tali was not an option for player romantic pursuit in the first game as the developers were unsure whether the alien characters would be emotionally compelling. Tali's romance event tree was added in Mass Effect 2 due to fan demand and her ability to express human emotion. This romance, if pursued in the second game, can be continued in Mass Effect 3. The romance event tree in 2 was written by Patrick Weekes. Mass Effect 2 lead writer Mac Walters commented that "[t]he choice should be in 'who' you romance, not so much 'how'", with each of the characters having different-natured romances depending on their individual personalities.
