I have gone backwards in my delta force experience having bought DF#-landwarrior first and then buying up the first two just to have more missions to play. It is certainly been worth it! All the delta force games take place out doors which makes them different. It's realistic action were you have to snipe your way around the perimeter to make your way into a camp to complete your mission objective. Of the three delta force games i own i think df2 has the most original and interesting missions.
