Urban Rivals. No one is talking about that game anymore. It used to be an amazing browser game. By now it's even on steam, but apparently they cut a lot of the animations so the crowd isn't happy about it. The card artworks are cool and the gameplay (was) fun. I don't know if it's still the same, as live games tend to change game mechanics.
Every other game I play('d) is mentioned at least sometimes (once a week).
Even stuff like Gothic, Golden Sun, Ragnarok Online.
