So there are multiple reasons why I don't want to do early access on Steam:
1. Once I release the game on early access then that's it, the entire game is now spoiled on youtube.
I'd rather leave that part until the game is finished and fully released, because spoiling the entire game on youtube is of course inevitable.
2. Releasing as early access means I'm going to release the game in an unfinished state, which is something I don't want to do, I want it to be as finished as possible before release, I'd of course have to fix bugs etc after release though.
3. I'm not really a fan of early access since it has not been getting the best reputation since it came out.
There were quite a number of games that used this in ways that were not intended, at least at first, I'm not 100% sure how it is nowadays.
So yeah, there you have a few reasons, I could probably think of a few more but right now that's all I got.
