I just wanted to add this to encourage undecided players to give it a try. Don't worry about those "bug" reports that say the game is unplayable or you can't finish it due to gamebreaking bugs. That is not true. There are some minor glitches, but nothing to worry about. I finished the game (again) yesterday and could do all quest, unlock all research except Swarm Probe Supressor (which is totally unneeded to advance your journey) and trigger dialogues when necessary.
