Two things really bugged me about ME2. Firstly, you've got this hyper-advanced AI on board, yet you have to scan planets manually, inch after painful, agonising inch. Secondly, you've got this hyper-advanced AI on board, yet you have to MANUALLY FEED YOUR FUCKING FISH! One of the most advanced, futuristic pieces of equipment in the galaxy and you can't even ask the thing to check on your fish if you forget.
Jesus H Christ on a stick, Humanity, if you can't even figure out how to do an automatic fish feeder, what hope has the galaxy really got?
Also, I feel ripped off. The only reason I sat through that hideous, painful romantic sub-plot dialogue was to see that Quarian's face. What do I get? Precisely squat! I hate you, Bioware.
Ok, make it 4 things. Now that I'm starting again from scratch, why couldn't they have done more of those vacuum sections? You get one little 2001-esque sequence at the start, then nothing else, ever.
