Ocarina of Time - 21338 [74.60%]
Wind Waker - 7264 [25.40%]
Majora's Mask - 14739 [53.30%]
Twilight Princess - 12916 [46.70%]
Epona's game crushes the King of Red Lions's game, and -- while Epona's smaller appearance won out afterall -- we still see TP did a fine job.
This is now the second site that had Epona's main three games be three of the LoZ-franchise's top four games (with LttP being the exception both times). GameFAQs proved it first, and now IGN's in the club too. I'm curious if G4 would have done the same thing too, since they just had LoZ win their series-contest recently.
This assumes WW wasn't inaccurately SFF'd below TP due to facing OoT or MM. You might be able to make an argument with MM on this site, but trying to get any strong comparisons through OoT (for WW or TP-through-MM) is very difficult, especially off GameFAQs where we have nearly no other references to make.
Whatever the case, Epona's games have been proving themselves lately.
