subversus said:that's a valid argument but bydestroying another Reaper threat, they've obtained the knowledge about their race which they can use in the upcoming battle. So it does sound like setting the stage for ACT III to me
We don't know what was on the data disk we got from the Collector Base. Honestly how people view ME2 in the future is going to depend on ME3. ME3 will either invalidate ME2 or show how good the setup was for the entire trilogy. It's hard now to view what will be important, if half our squad comes back from ME2 and ME1 and actually serve an important purpose plot-wise, then there was a purpose to the recruitment missions. If they use the dark matter they continuously brought up in Tali's mission as some sort of weapon then that would help tie ME2 into the trilogy.
