Reddit reviews Sonic Genesis

If you're a fan of the games, I'd start with Sonic Genesis, simply because it follows the original games quite nicely in terms of level progression and style. Its nice to see the original 16BIT levels in nicely drawn comic art. This story was somewhat of a soft reset for the series so it's quite a good jumping on point. If that retains your interest, you can then choose to go back to see what lead up to the reboot or just keep reading on from that point.

Also, it doesnt hurt that you can buy it in a really decent looking hardback book
