Try doing a game with pokemon like graphics think fire red/ leaf green, the way you make the map and sprites. Make sure if its an Adult game you got Adult content example being oral vaginal anal sex nudity ect ect<<<< and if you need story plot ideas I don't make games but can write pretty good I would be happy to give you some for what you like or are interested in doing. I seen an old pokemorph game in the style that was really fun and furry genre games are lacking good quality ones so that would be a start....
