Basically every game has been "excelled" in popular opinion - Modern Warfare 2 was the biggest entertainment launch ever. Even if you break it down by genre there are plenty of newer games that meet at least some forms of "best" in terms of public opinions. If you mean "unexcelled" in terms of grumpy games reviewers with long memories older games might have a shot, but that just puts Shoggy or MTW back into play.
