Lukasz, I'm sorry, but I think you are making a mistake by not updating AoCII further. There's no workshop, there's no iOS, the game is buggy, some people can't even launch the game, it could use more scenarios, etc. Wouldn't it be better to wait on starting on a new project for just a little bit longer?
I really hate writing mean messages to people, but honestly, with no offense, this just has to be said.
Abandoning AoC2 for you is a really, really big mistake. You develop a game, publish it and abandon it after a short while, saying you've "worked on it for long enough". Do you know what this tells relays to your customers?
That you don't care about them. That you care about quantity over quality. You promise features but don't keep to your promises, not even fixing bugs. This just simply tells your customers what to expect of your next project - a half-broken game with bugs that aren't going to be fixed by the developer.
If you want to start a new project, first you need to gather interest for it from the last project. Completely abandoning your last project half-finished is not at all a good way of doing so.
I'm sorry that I just went all-out, but it was something that just had to be said. I loved the idea of AoC2, I saw great potential. All you needed was to fix bugs, improve the editor and add some demanded features. Your player base would then understand that you care for them, you listen to them, meaning they'd be interested in your next project all the more.
Believe it or not, continuing support for AoC2 will do more for your new project than actually working on it right now. Either way, I still wish you luck and good fortune.
