I finished up Tali's recruitment mission. The Geth Colossus was a joke. The only trouble to be had was getting to it. I also managed to finish Thane's recruitment mission too before shutting it down for bed. Thane's a great character, but I only went after him this early because I wanted to increase the number of Probes I could carry. I'm low on resources and I want to take as few trips as I can to those stupid fuel depots!
