This game is an outstanding realisation of the Battletech universe as it would be played on the tabletop. It is turn based and a good understanding of how the math works helps to do well early on. Once you have explored the official DLC there are some very good community mods that really make this game stand out. I have 200+ hours in the game (mercenary edition with dlc) and I'm not even close to putting it down. Check YouTube to see how the turn based system works. This is not for everyone, but you never lose because you have a low end pc or bad internet. You only lose because of your decisions or bad luck. I love this game and after reading the books and playing Mechwarrior as a kid, this is everything I wanted. Considering the cost of setting up the tabletop game this is the best money I've spent at GOG.
