PSA: if you've ever wanted to play an indie game made with unity, download it before january 1st 2024 or risk losing your chance! (for a list of unity games, i found this. can't say if it's completely comprehensive but it's a start)
if you're a game dev or aspiring game dev, i would check out unreal engine. it's widely documented, pretty easy to jump into, and free until you make over $1 million and then they take 5% above that- so if you made $1,000,001, epic games takes 5 cents. epic is a big corporation so they could pull some bullshit but it's less likely. and they have protection from future bullshittery if you stay with the current or older versions. beyond that, there are a ton of other free game engines out there or engines that are on the cheaper side (game maker for ex, only requires payment on export and is the game engine used for undertale/deltarune). so if you can help it, don't waste your time on unity!
