I love it too, but it bugs me that you cannot save in the middle of a mission and if you close the game (as in opening something else to return later) you are returned to the very beginning of the mission
I'm in the space buggy one and I have restarted it twice because of this
I really enjoyed this game, I did experience some bugs and issues with the auto saves but overall this game was solid and the missions were elaborate, entertaining and fun to play through again!
