Well, the ones I named are more "wargames" in the traditional sense: tanks and planes and stuff. But as I mentioned, the principles of reconnaissance and exploiting weaknesses are the same, which is interesting. For more computer-oriented wargames, I really enjoyed what I've done of Microcorruption (if you're into radare2 sort of stuff) and wechall is a challenge site tracker that has links to many other similar games as well as being a scoreboard that you can track your progress on all participating sites on. Or if you like competition, CTFtime.org is a live calendar of many computer security capture-the-flag competitions you can join. If you're interested in that but want to join a team, OpenToAll is a team that welcomes anyone to join and talk about challenges.
