It depends on what DLC you have and if you want to do 100% completion or not. No side quests and the main storyline can be completed somewhere around 18-24 hours give or take. All side quests can take well over 50 hours.
Mass Effect 2 is a first person shooter game. Though doing the campaign can take you about 12 hours, depends on if it is rushed through or each task is completed.

Mass Effect is only a trilogy. Therefore there will not be a Mass Effect 4. Sorry budAnswer 2The above answer is no longer necessarily correct. Bioware has confirmed that there are still stories to be told in the Mass Effect Universe and that there will likely be a fourth game. It is unlikely though that ME4 would follow Shepard again, and it is unknown if it will take place before, during, or after the events of the main trilogy. There are however rumors that it might take place during the First Contact War.
