The Little Things 2.0

Which matches nicely with the mounted krogan head found in DAI.  Reasons why people believe Thedas is somewhere in the ME universe.

That's interesting.  Never knew it myself.  Though, I personally think thermal clips were a step backward.  I'd rather my gun overheat and I either take cover or use biotics (assuming I have them).  Or just switch to a different gun.

If Anderson is councilor in ME2, the subtitles will say Captain Anderson instead of Councilor Anderson

Never really paid attention to what Zaeed said about his quest when you first meet him. Finally read it and now things make more sense. Zaeed says that his goal is to help Eldsfell-Ashland remove the Blue Suns presence since they'd turned the workers into slave labor. However, his actual goal is just to kill Vido Santiago. This means he was willing to default on his contract with Eldsfell-Ashland and wantonly murder the workers just to get his way. I never realized he was being so deceptive and now understand why Shepard said he was ruining the mission (which I'd never bothered to figure out).

It is. A smaller version.

I found out why Bioware have been trying to pass up Turians being birds.

For the first time ever, I heard Harbinger say "Preserve Shepard's body if possible." I wonder why they're so interested in it? Is there really something special about Shepard?

You can go to engineering and Anderson's quarters to hear comments after Eden Prime.

The Citadel Tower Layout looks like a Reaper

I was just watching Miranda's Loyalty Mission (I'm not playing ME2 right now) and it hit me... Niket tells us point blank that Henry Lawson is "the richest guy in the galaxy." This would mean that TIM isn't.

Yes... maybe even the benefactor.  He was "in the know" about the Reapers through his work for TIM that was revealed in ME3 (but had been obviously going on for some time before that).  I'm being very speculative here... but maybe even he intended to kidnap Oriana to put her on Hyperion and get her out of the galaxy before the Reapers hit.

That's something I'm not sure I really believe though since he winds up essentially working with Cerberus in ME3 changing the people on Horizon into husks.  I wouldn't have put it past TIM to have mislead Miranda on that front just to ensure she stayed estranged from her dad.
