Looking at the boosty profile for tiers it specifies as a perk "Also access to 2(or 4) dlcs after their release" What's the details on this? Is it content not included in the game itself (tiered paid content?), or content to be released at a later time they'll simply have earlier access to?
Dls will be released at different times and actually complement the game.
There are 5 of them planned:
1-Bad Sam (the story of what if Sam all the time before college grew up and entered it not with small size)
2-Heigh growth DLC (since in the future will be released version 2.0.0 in which you can choose one of the clubs in which Sam and her friends will go, which will lead to the fact that the story will be changed dramatically depending on the choice. There will just be another choice to focus on high growth of the character)
3-Futa DLC (this is a massive dlc that will bring content to all available branches, include heigh growth dlc. It will be the most extensive and largest.
4-Past Curvy Town. This dlc will talk about the time when Mama Sam was in college and I'll just show her story.
About those subscription levels where you saw the information about the dls. Those subscription levels need to be bought once. After you give us a special role in discord and permanent access to all content on curvy town. Depending on the level, you can get 2 or all 4 dls for free.
The dls themselves (except for the first one) will be paid. Since the work on them will be huge and some of them will include almost as much content as the main game.
