Operation Flashpoint

While I have been taken to task on other forums about my opinion of this game.....here goes.

Graphics?OK.......Changing weapons?A little slow.........Menu/Very good. This game is NOTHING like Cod MW, so I'm not sure why anyone mentions it. GRAW or Vegas 1-2 is much more accurate description. On "normal" mode you can be injured, then killed very quickly. I don't have a problem with that, but after running 1.6 miles to SAM SITE, scouting the area, moving 3 of the squad members into position and "engaging" it's somewaht annoying that after I've been killed (which will happen often) I now how to go back 1.6 miles and run through the whole scenario all over again (20 minutes maybe?). Someone suggested the game would become just another "Run N Gun", but my point is why would anyone believe running across 1.6 miles of terrain and nothing happens fun? Less checkpoints at a higher difficulty setting maybe? More checkpoints at an easier setting? What's the big deal? I just think you limit sales of the game by the extreme difficulty of settings.
