Zebbi man i love you but omg.. please stop stressing about a splash screen.. lol no one cares.. gamers especially.. there are unity games out there that make a shit ton of money and they still have the "made with unity" splash. unless you're doing a job for a client who is really picky about it.. you just explain if they want it removed they have to pay the fee.
I'm not bothered, but clearly the developers thought it was overpriced enough to reduce it for a promo and they must think it's important enough to include, they've set the value of the splash, not me.
