I've been wanting to work on networking for multiplayer online browser games (but not io style more traditional game style) but it just seems like a ludicrously challenging problem for the kinds of games I want to make. Some are real-time, some are turn-based, all would definitely want an effective system for handling disconnects and latency and data persistence. Trying to work through these is like far harder than any "hard" problem I've seen on leetcode. It actually makes me feel like sick to my stomach when I spend 12 hours on it without making a lot of progress
