Sekai Project 2026 is a $15 bundle. These are visual novels with various gameplay styles (there's a dating sim for example) and grades of NSFW content (some games have 18+ DLCs). Sekai Project has a lot of games out so this is a grab of mostly old games.

I own some of these probably from a previous bundle but I haven't played any. Still, $133 retail that I don't own so $15 is worth it.
