Old IPs... Rise from your grave!
I would love to see a new Space Harrier. With today's technology it would be looking great. Get ready!
Also, a new Segagaga set in the past where they where still producing consoles and how the player would have chosen to save their console business
And I would kill for a Marvel vs Capcom style Sega vs Nintendo beat'em up. With Alex Kidd, Shinobi, Starman, Ax Battler, Rent-a-hero, the Centurion from Altered Beast, several characters from Sonic, Streets of rage and Phantasy Star series... They have more than enough characters to create a great rooster of fighters here to compete with Nintendos Stars
