Even Julian Gollop's latest game (Ghost Recon Shadow Wars) used the move/shoot turn dynamic and it worked out great. I have no problem with losing TU's.

I'm so excited for this game. UFO Defense is my favorite game of all time and I put lots of hours into it each year, even still. I'm somewhat concerned about the squad limit. I'm more concerned that now that they are making an X-Com game that I'm actually excited for after all these years, that I'm going to die or the world is going to end.
