Let's make a comparison first:
Engine: Needless to say, CSOL is good. Valve software in the United States and NEXON company in South Korea jointly made it, CF garbage, and Tencent made it according to the texture. Of the players in 10, 9 are on-hook players.
Plagiarism: CSOL teamed up with CS Original Company and South Korea's NEXON, and American Valve Software (the original of CS) also gave copyright, while CF copied CSOL, which is basically known to many people.
Bloody+violence: CSOL is bloodier and CF is more violent.
Spend money: As long as you are a player who doesn't pay attention to roles and clothes, CF is quite suitable for you. A knife only needs more than 3000 CF points a month. If you are polite, you will be very lucky to challenge. Last time I opened a bronze Malay sword, other boxes will also open RMB guns, and the activity is also to give you guns. There are a lot of CSOL activities. Some players get a lot of good guns from activities, but less guns are sent out in challenge mode. Do you think it is more comfortable to use a sweat gun?
How many modes: There are many CSOL maps, but few modes (basically one map is added every half month). There are many CF modes, but the picture is average.
Playability: CF is strong in children's eyes, ranking a little higher than CSOL. In the eyes of ordinary people, CSOL is playable.
Image: CF uses high-definition map, and CSOL uses animation. CF has a high definition, but the battle picture is not as realistic as CSOL.
Number of guns and close-range weapons: hundreds of CF guns (some people say Tencent is trying to cheat money) and dozens of CSOL. If there are knives, there are now 6 kinds of CF (sometimes 7 kinds of CSOL). I like CSOL's close weapons. CSOL has hammers, swords and bronze swords, and the prices are reasonable. CF is expensive, and they are all knives, not hammers.
Confidentiality: CF is QQ number, and CSOL is Century Tiancheng. Needless to say, as you know, the probability of QQ number being stolen is high (but the confidentiality of QQ is not worse than Century Tiancheng), and the probability of Century Tiancheng number being stolen is low. QQ is a little later than Century Tiancheng.
