For dlc content it is in the patreon of the 5 usd tier so if u want with the dlc it is a total of 23 usd.
FMC has less art than MMC by about 25 comic panel style cgs total (all basically in the cut intro) as their intro for the game start scene is cut due lost files that but other than that everything is the same. You can also compare in the demo first to see what u miss as that intro and 2 cgs before mc change uniform is the main difference, other than that the count is the same
if u have doubts or on a budget I suggest buying it on sale during halloween as I always have a sale during that time at least for the main game, my patreon tiers don’t change. Hope that helps, sorry for the confusion!
