I know Shortaholic did tiktok marketing that went well, for simppixelI mean, you can easily get players if you create content for the network yourself and use tiktok and youtube to build up your network on social media which will save you a ton of money but it's a slow approach but once you start getting decent views and a few viral videos, you can easily hit a ton of players daily so I think 1000$ is a good amount of money for stuff if you don't go for exclusive builds right away but rather work yourself up to that.
