Clumsyorchid, Sega community rep, was already asking me about Virtua Racing, Scud Race, Daytona 2, Sega Rally etc when I suggested them on their Daytona blog.
We can get these games, they just need the feedback and to see some enthusiasm for them.
Sega Rally + Sega Rally 2 could be released in a combo. Maybe Virtua Racing and Indy 500 together though that would require another license.
They already have the Daytona license again so it makes all these sense in the world to go ahead with Daytona 2.
Super GT aka Scud Race HD is glorious enough to be sold on it's own for $9.99.
