I've been working on a 3D game engine - Cutlet Engine. I've made a tile-based 3D world editor for it.
A lot of work went into the engine so far, although, unfortunately there is not much action to see yet. Hopefully it is alright for me to post this at such an early stage.
A rundown of my engine's map editor features (with more pretty pictures!)The game that I'm making with this will be an RPG with a lot of focus on freedom of choice, dialogues, and tactical combat. The combat will be pausable, to give the player time to plan his actions (think Baldur's Gate or Dragon Age: Origins). I'm planning to have an open world set in a fictional modern-times anarcho-capitalistic state. The players will have the ability to train several skills, such as stealing and hacking. I want there to be many ways to finish quests with different endings.
I know this sounds ambitious, but I am confident in my programming skills. I'm not as experienced in modeling, though, so the graphics development is going slower.
