What's more fun than giant mechs stomping each other into oblivion? Harebrained Schemes' take on the long-running Battletech franchise. It's a winner when you need a game that goes on for a long, looooooong time.
While the campaign itself is somewhere in the 60-70 hour range, it's what comes after — when the full map opens up — that's a real time sink. Whether you're an achievement hunter, or you're just trying to get all the parts to build that elusive crab mech, you're facing down hundreds of hours of missions.
While such a glut of content got a bit stale at launch, additional mechs, travel events, and new mission types have since been added with free updates and paid DLC. If you quit after 120 the game first dropped, now is a great time to jump back in to see what's changed. Maybe even add 120 more.
