Data parser from games / programs?

Question

Parsing

You need to constantly parse data from the game (let it be ArcheAge and Lineage 2), tell me if it is possible to get open information from them (prices on auction, some messages from the chat), if possible, what tools are needed for this.

Answer 1

Either write an alternative client for this game, or use a sniffer and analyze its output. In both cases, it will be necessary to parse the protocol of interaction between the client and the server. In short, it's all very interesting! :)
