I really like the Call of Duty/Battlefield series, but I prefer the more modern type of game-play. I currently play "Americas Army (level 93/100)," as my stress relief when I have time, but I see/hear that Call of Duty 4 will have modern tech, then I will end up playing this too. I won't give AA up because I will get that 100 honor. Might take me forever, but I will do it!
The age verification is because the game shows depiction of violence. The game looks cool and I can't wait! If you get it for me, then I'll be your friend to the end :)
