Well i started with something relatively easy.
A round based battle game at Visual Basic.
I am currently stucked at the problem, how to transfer local variables like Heal Points, Attack and Defense, to calculate the damage in a sub...
Whatever, i rather die, than program something like Fortnite xD
I would strongly advise you to start learning Python - it is easy and nonetheless very powerful. By the way, we use database to store variable for a longer time.
