User blog:Tali's no.1 fan/Spin-off Suggestions

Someone on YouTube posted the idea of a spin-off game focusing on what Garrus did between ME and ME2. Personally, I'm 100% in favour of the idea; I've already been hoping for some missions in ME3 where you play as someone besides Shepard. However, such a game may be too short. So, any opinions on a spin-off featuring stories with numerous Mass Effect characters? Imagine...STG missions as Mordin, Assassinations as Thane, hunting Morinth as Samara, quarian special operations as Tali, "Impossible missions" as Zaeed, maybe even the adventures of Legion.
