This trilogy sits happily in my All-Timers list and, while it understandably might anger purists of the genre, this does firmly fit into so much of the Immersive Sim genre.

There's very few games for the price-to-gameplay value this trilogy has. It's honestly quite stunning.

For people who want to jump in though for the first time: Do yourself a favor and turn off all mission story guides. Just drop into a level and ... work.
