I meant to write TCG* ! Sorry.
I have had some smaller projects in UE4, but nothing serious so far. I had a really cool idea about a card game based on a PC game I really like, and I was wondering how hard would it be to implement a turn based card game like yugioh, heartstone or antyhing similar? With or without the online element.
All you have to worry about is logic. Card games and such have alot of logic that needs to be made. If you can, download the poker example project if its still available. You can get an idea from there of how much work it takes just to make a poker game. I am trying to bring a board game I really like to life with UE4 and the logic for all attributes and characters can get overwhelming.
