What a stupid topic. To me, every gamer that respects himself as such can't put forth a single video game/series as being ''the best''. Video games are too diversified to be rated as arbitrarily as that.
So my answer is no, of course not. It may the best of some sort of category, like ''realistic shooter'', but in any case can it be qualified as ''the best''. No game can, it's as simple as that.
