Right now I only have one game idea that I have to do, one of those that are going to make me a millionaire. There is really only one aspect of the game that is difficult to do, but that part is on the other hand very, very complex. But now that I've put the shitty games behind me, there are a number of technical things I want to improve on in order to make a fantastic game:
- rendering;
- multiplayer*;
- modelling, skinning, rigging, animating (humans).
* Interestingly I've added a ton of networking code. Never used it. What a waste of time.
