My son prefers Sonic Sega All-Stars Racing

Fun game... lots of depth and odes to Sega lore

The first one let you unlock classic Sega tracks and you could select from multiple music tracks for each race track

Back again is the wonderful Sega soundtrack

The game features familiar Sonic characters as well as characters, tracks, and tunes from other famous Sega games such as Jet Set Radio, House of the Dead, Golden Axe, Crazy Taxi, Super Monkey Ball, Shinobi, and Alex Kidd

You try to gain as much XP as you can by winning or else you get less XP for failing to win
