Well... I'm developing a game called Scarlet Moon over at spankingrpgs.com. You take the role of a superhero(ine) who develops superpowers one night and decides to do what any self-respecting college student would: become a superhero.
It's written in third person, and while there is a slight bias in favor of the main character getting their fanny whacked, they have plenty of opportunities to whack some fannies as well. I'm also striving to make sure every spanking scene is optional, so you can play a pure dom (or sub) game if you want. It's *very* American though. Lots of paddles and paddle like implements, not a cane in sight.
The main character is highly customizable. You control:
Their gender, bodytype, hair color, skin color, and a bunch of other things as well as what clothing they wear at any given time. These also have a slight impact on the in-game text.
It also has a turn-based combat system. I tried to make the combat challenging, and for most fights winning is optional. You can also disable combat if you don't care about it (in that case, the game asks whether you win or lose each fight).
It's still in development, but three and a half episodes have been released so far.
I also have a couple of smaller CYOA games up there, one written in Twine that takes place just after episode 2 of Scarlet Moon, and the other straight up boring HTML that takes place in a different setting. Neither of those let you select gender, though both are also written third person and give you a few opportunities to whack or be whacked.
Most of the choices are cosmetic choices. You can select how your character reacts to a situation, but their reaction doesn't affect anything. However, there are choices that do affect how you move through the game. Each episode ends the same way, but the choices that matter change *how* you move through the episode. Generally, I try to have two significantly different paths in each episode. Each path tends to focus on different characters and develop different subplots. For example, in the second episode you can choose to raid the villain's base or get help from a local CEO. Choosing the first path develops a subplot involving government agents, while the second explores the character of the CEO a little. The goal is that by selecting different paths you experience the story from different points of view, even if the overarching story itself is mostly the same. |
