Oh hehe yeah I get you. Yeah well it seems like many people like to have the classic Zone mode available, others like to see some improvement. So yeah, maybe it's best to place both into the game.

Single Race, Speed Lap, Time Trial, Endurance, Tournament, Zone, Platformer, Head To Head

That would make 8 different race modes. Actually a lot already Main stuff from Wipeout in it and Head To Head, Endurance and Platformer would be some extensions Actually I am pretty satisfied with that. And I think too many modes would be confusing at some point. So yeah, I like this list.
