I'm playing the game right now, I just finished mission 4 of the first campaign, and I've two wishes to make :
1. A warning when launching an airplane from a carrier/airport with almost no fuel. I use one, make it land before it gets out of fuel, repair it, and relaunch it... and forget to refuel it, and boom it crashes. Feels very frustrating and not realistic.
2. A way to see details about achievements, like say Shephered, it would nice to see how many missions we did "with less causality than average", and which ones (so we know which ones to replay to get the achievement). I get the feeling I did my first 4 missions with less causality than average (at least, if I read well the debrief at the end of the mission), and yet it's not unlocked, so I would like to know which ones are validated and which ones aren't.
