I never played any of the older games so I can only view HR's endings within the context of that game
I don't think HR's endings are that different from ME3. Both games lock you into choices forced upon you by AIs. The stock footage is only slightly different between the 4 ending in HR. The "explosions" in the 3 ME3 endings are just different colors. We don't get to see the results of any of the endings in both games. ME has a leg up because we get more than just a 2 minute monologue.
Not gonna start with AC. Bad cliffhangers don't make good endings
