Ok, so imagine that you're hungry and you come across a sandwich shop that has your favorite sandwich for $15, but the shop next door has the exact same sandwich for free. Which sandwich are you gonna eat?
No, wait, that's not important. Most people are gonna eat the free sandwich, so even if you eat the $15 sandwich, you're statistically irrelevant.
Yeah, maybe some people that weren't hungry are gonna get a free sandwich, but the people who were hungry are also getting free sandwiches, which means that the guy trying to make a living selling $15 sandwiches is gonna have to close shop unless he starts lacing his sandwiches with cocaine.
Maybe I'm bad at itch.io but it looks like they are both free. Lemme offer another analogy.
Your and your friend have sandwhich parties and one day you compare notes. Your friend's sandwich is really good, so you make it yourself and add some things. Now you really like the sandwich so you throw a sandwhcih party with the new sandwich and tell everyone it's based on your friend's sandwich.
Then your friend asks why you coppied his sandwich and you're a jerk about.
I didn't realize he wasn't trying to sell his game, so I guess we need a different analogy.
Ok, imagine you and your brother are making a website where friends can post about their lives and keep up with each other during and after college. You're pretty open with your project and then one day the one weird guy in your friend group launches your project without consulting you. The project takes off and makes billions of dollars. You sue the weirdo and he gives you some money, but you're still pissed about it. Did you get Zucked?
Exactly. It feels more like making a snake clone with fun features. Second guy learned some stuff, but was a dick about it. Ultimately no one was hurt tho and this doesn't seem like a big deal
