Whoever decided to rank Far Cry 2 6/10 didn't have the guts to put their name on the article. That was probably intentional as the author -- obviously intimidated by the gameplay of fc2 -- would be hunted down and cremated by fc2 players if his name were disclosed.
Yes, there is a lot of driving. Er, well you also have the option of using boats instead of vehicles, or, if you can't handle the fact that the landscape is crawling with coked out kids in jeeps with machettes and machine guns, you can take a bus and avoid the types of difficulties you'd likely find if you were driving around by yourself in a land torn by internal gang wars and without an effective government. But, of course, when you do drive or boat, you also uncover side missions, find new weapons, find cash (er, diamonds) for purchasing new equipment, and learn the best routes to get out alive when things get heavy.
Every single first person shooter has issues with weapon realism and far cry is not different in terms of having problems with realism, just that the realism tweaks in FC2 are a little different than how other games have grappled with weapon realism. Also, there have been a couple of patches addressing weapon accuracy, hit and damage modelling, so, without knowing what patch the author was running, it's hard to say that their opinions are accurate for the game as played on the popular servers on the net.
After maybe 20 to 30 hours of single player play, I still have not completed the campaign .. yet I'm still playing the campaign when I have time. The setting, gang ravaged rural africa, is more realistic than many settings invented by publishers to create an action packed killing environment. The horrors of real world Somalia or Mogadishu come to life in a way that raises the conciousness of the player in a way that more fictitiously based shooters can't match.
The map editor is easier to use than any other map editor for a fps I've ever used.
THE BIGGEST PROBLEM WITH FC2 IS THAT THERE ARE NOT ENOUGH PEOPLE PLAYING. Thats why the reviewer, who doesn't want to identify themself, ticks me off so much with his 6/10. It's just not a fair figure ... it's just a bad review by some wimp who prefers kiddie crack fps to strategy fps.
