Goddess' Whim, Corrupted Kingdoms (on subscribestar) and Afterlife Harem are ones I can think of off the top of my head. Or you can buy Koikatsu Party on Steam and make your own characters using the exact same animation tools they use and make custom scenes yourself.

I’m playing One Twisted Fantasy right now since it has a in game card collecting and battling system with a type of currency where you battle monsters to collect xp and chest. The chest drop random cards which you can upgrade or sale. You make your own battle deck with the cards. The download is under a gigabyte. This game could take days or weeks to play if you just battle and collect cards and upgrade your deck. 😉
