Great game and definitely worth a play-through, which I managed to do in two sittings. The biggest issue really is just the presentation, which could have been done better, but since you're a mercenary, context and story doesn't matter too much, does it? It's a perfect level of challenge, as by the end of the game, I had only lost five missions. If you find the controls hard, just give it another hour and really experiment with the customization; after that, you will be over that hurdle easily. The variety of missions and how short they are will keep you coming back, and the flavor text before each one really immerses you that much more to just keep pushing forward.
