>>714570087>it has to be doneit can take a decade to make an engine, you can recreate the functionality (not all the cards, but the functionality) of Slay the Spire in an afternoon in unity.
You have to have a really good reason to make an engine, and there's only 3 reasons
1. you're rich enough and dont want to pay royaltees
2. whatever you're doing is physically impossible within an off the shelf engine.
3. you like making engines and not video games
anything else is a massive waste of your time and talent, any time spent reinventing the wheel reprogramming save file serialization is time you could have spent making your game.
