Um, there are a bit too many to list... But some of them are like:



- Getting Tali either exiled or found innocent and deciding whither or not to give the Geth data to the Quarians.



- Upload Cerberus data from the captured spy to either Cerberus or the Alliance.



- Keeping or destroying the work on the Genophage cure.



- Rewriting or destroying the heretic Geth.



- Destroying or giving the Collector Base to Cerberus.



- Choosing Morinth or Samara.



- Letting Garrus kill Sidonis or letting him live.



- Who survives the Suicide Mission.
