Mechwarrior 5 ****ing rules! It's kind of barebones in that the missions are repetitive and in between missions there's nothing to do but tinker with mechs, but if you want a mech game with intentionally clunky mech sim combat where you develop a mercenary squad of mechs and pilots then it is absolutely addictive. My only complaint is that my current best, biggest mech isn't slow and lumbering enough.
