Mergeware 1.1 (English)

Mergeware throws you into a weird situation where you wake up in another world with zero memories and a body that isn’t yours. Turns out you’re some kind of .Exe entity, but the friendly kind who wants to help fight against the evil ones terrorizing the place.

The hook here is the fusion mechanic where you can merge with allies to boost your powers and become stronger. Problem is, you have to convince people to let you basically possess their bodies, which makes for some interesting social dynamics. The amnesia setup works well since you’re figuring out this strange world alongside your character.

Royal Harem keeps things straightforward with the storytelling. If you like games about supernatural possession with actual consequences for your choices, this one delivers without getting too complicated about it.
