Anamon: Reclaimyourgame sure lost their balls. I remember when they were really on the player's side with their lists and everything. But now they have shifted their focus on trying to pass some sort of a "customer-friendly DRM" approval seal. Not a horrible idea in itself, but if you read their criteria, they state that they even certify online-activation as customer-friendly, as long as it does not have activation limits. That was the end of that site to me. If giving some company the right to wipe out my expensive games by the push of a button is their idea of customer-friendliness, I guess I'm just a gamer that is very hard to satisfy.
As for Steam, I have quite an on/off Internet connection, and offline mode always worked surprisingly well for me. No need for updates or anything that would require me to be online in order to play offline... I've heard of a few people having problems, but I never thought it was a wide-spread problem (as you usually don't hear from the people for whom it works).
Just to be totally up front and open before starting, I am actually a former admin on RYG.
You pointed out their testing and...yeah, it doesn't make a lot of sense. Their testing documents show a lack of consistency across all testing. They pass a game for using activation limits that are, in the words of testers 'easy to trigger', while failing it for leaving behind a couple of registry keys that do nothing but maintain one of those activations. It doesn't make any sense.
Beyond that, there are clear biases that have remained in place from the beginnings of the site (the prime reason I walked).
