Here's a good one: in 290 years since the Morning War, the Geth have not installed integrated weapons systems in their mobile platforms, and they have only forward sensors. Apparently they are not big on design improvement. One would think they would have at least installed a death ray, but I guess General Electric beat them on the patent.
Here's a better one. Why did the get go BACKWARDS in tech between me1 and me2? Even the codex notes that the organic design of Hoppers wasn't by quarians, meaning the geth are improving themselves. Not to mention their plasma based weaponry. Come me2 and 3, though and the only units they have are standard walk and shoot units. No shields no hoppers no drones, nothing. And they were the first to go back to the highly inefficient ammo system. Did the feedback that took out sovereign cause an AI loop with the geth or what? Seems like it rebooted them back to factory settings lol
Come to think of it, why doesn't the universal translator translate James' Spanish? I can understand it not catching Boshtet, a cuss word of a non council race, but one of the most common languages of humanity?
