My mate introduced me to this a few years back now, it wouldn't run on my system at that time but I held onto it and started playing when I got myself up to date, if you enjoyed commandos you'll love this, I am still yet to complete the UK campaign... Damn searchlights...
I am a HUGE fan of the Gothic series, if you have a lot of time and really want to lose yourself in another world Gothic 2 is the way forward, I have played this game more times than I can remember, yeah it's a little buggy but for it's age it's phenomenal!! Totally free roam and MASSIVE!
