If you want to take advantage of all the features Sega offers with Sonic Origins, you’ll need to purchase three DLC, as certain modes, features, and even some visual innovations will be sold separately as DLC.
The table posted on the game’s official site shows which version you will have if you buy:
Now let’s start by saying that even the price of the game on PC (Steam) is 429 TL. With all that money, you want to own the whole game, but you’ll also need to buy DLC;s called Start Dash Pack, Premium Fun Pack, and Classic Music Pack.
Currently, the cheapest way to buy for all DLC;s seems to be to buy a Digital Deluxe Edition, and its price is 475 TL. However, as you can see in the table, if you want to have the Start Dash Pack package and take advantage of the features that come with it, you need to pre-order standard or digital deluxe. This means that if you don’t pre-order, you won’t be able to take advantage of start dash pack content even if you buy Digital Deluxe later in the table above.
It’s hard to see why Sega chose to complicate things so much.
