This is a "simple" game in the sense that you can start playing it after maybe 2 minutes of exposition. And then you just go through the missions and discover. I like it. The technical realization is very well done, graphics look good and are very performant. No loading times. Small install site. I played with mouse and keyboard and found no issues. I suspect many of the earlier reviews that speak about difficult controls were reviewing an earlier version, ie the problems might have been fixed. This is not a forever game, I guess you can probably play through it on a long weekend (the base game).
