I loved the game and much preferred it to the utter dreck that was Red River.
Have to agree. OFDR is slow to start, those first 3-4 missions just aren't all that enjoyable. The later ones are excellent. I love the one where you rescue the pilots and have to escort them to the extraction point, and securing that point. The one that's mainly observation at night to laze (lase? Laser?) the target and assassinating the enemy commander...and extracting...is even better.
In Red River, it was like a typical ubisoft production with an F bomb every other word. I can't comment on the entire game since I only did a few missions, but they were pretty dry "stop, shoot a few, get on the truck...repeat" type missions. The annoying banter that was blissfully absent in OFDR annoyed me to dropping the game.
I do wish OFDR had more guns with options for scopes etc., kind of sucks having to pick up a Chinese rifle.
Play through the game quickly on the easy setting, just to get the missions unlocked. Then replay the good ones on the harder setting.
