Graphics don't make a game. And the hackers weren't so bad, it's just the game itself isn't a good FPS.
I actually used to play the game for about 2-3 years and I gotta say it was actually one of my favorite games because of the clans and how you really could outmatch anything with justusing skills (or hacks).
But then there were times in that game where hacks were pretty much unavoidable and the only way you could play was to hack since more than 50% of the community was hacking. But rarely aimbots went free so even with hackers if you were good enough, you could beat them out.
Back when I played I used to mainly use the L4A1, then after the Arctic Wolf mod came out I bought that for permanent. I was really disapointed to find that the arctic wolf and the L4A1 were COMPLETLY different guns (in terms of the feel of it) even though they were supposed to be just a reskinned version of each other, which as a result messed up my game and Ive never gotten used to.
The reason I quit combat arms was that after a while people were getting tired of all the hackers and Nexon not doing anything about them, so they would quit, and the amount of exp given per match was inflated later on so my ran that I spent 3 years making became easily achieveable in a month. So I was at a low rank when I used to be high, and none of the people I used to play with still played so I quit as well.
