I actually thought there was more conversations in ME3, than ME2...At least I love there was more interaction within missions, so I was happy.
The bro day out with Garuss and the Garrus, Tali acknowledgement at the end made the lack of meaningful conversations moot for me. Those two and the mission banter, talks were perfect and enough for me.
Maybe if all game companies made bad endings we could solve this world's problems.
