AploVVare Collection tries to simulate the feeling of having a Megadrive with a lot of cartridges to choose from (currently 23, they keep adding more and more). These cartridges are gamejam projects/short games the devs made and packed them in this neat little collection. Games can be hit or miss and often experimental but they're often charming enough to not be just a prototype that must and should be forgotten because it's so raw it's barely anything.

The biggest highlight of the collection is the DLC that simulates the 32X; an addon for the Megadrive that basically attempted to "upgrade" the console so you didn't have to buy a new one. What does that DLC do? It adds +18 content to every game.... yeah...
the developer AploveStudio is quite horny and they don't hide it! The games themselves without the DLC can have some horny content, but most if not all of it is contained to the DLC. From simple nudity and sprite/art swaps to new synergies and effects and characters, the +18 DLC is by far the most relevant thing about this.

*I forgot to mention this and I don't know where to put it, AploveStudio's characters are all over AploVVare Collection, but it's fine if you haven't played any of their games. Hell, you might meet and know them this way a bit more easily.
