I don't know most of those, but I think the point is whether video is being the defining feature of the game. Chess played on a computer is primarily chess, not a computer game. Same with poker. A golfing or racing game isn't similar to golfing or racing, it's clearly primarily a video game. It gets somewhat blurry when you have a high-end setup with a cockpit that's being shaken while you drive a rally. Is it still a video game, or a simulator? I'd say the latter, but it's an edge case. Angry Birds is, to me at least, closer to a video game (though I'd say it's a different genre "mobile game"), because there's obviously not a directly transferred real-life version.
