CF and AVA are fun.

Personally, I think AVA is more fun, because AVA is more real, but it takes some time to get started and requires higher team spirit. If LZ likes simplicity, it is best to play CF, which requires higher personal skills and ignores the simplicity of coordination. It is easy to get started and has lower configuration requirements, almost simpler than CS. But AVA is the most authentic, with good image quality and engine, but the configuration is relatively high. The guns are basically recovered. But how long has it existed? There are fewer guns. Let LZ decide for himself!
