Welcome to the Wargame Nexus
This is an organized, PR-able list of wargame sites. If you know of a (reasonable) wargame site not on this list (and there are definitely some), shoot me a PR. I have nightly tests to detect sites that have gone down, but if you notice something I missed, open an issue!
You can aggregate your score across many of these sites by registering on WeChall.
