Noita is currently 60% off and is hands down the best game I have ever played (kind of). It is ridiculously brutal and you will die very often but you have the potential to get ludicrously powerful as well. The game will cheese you so don’t be afraid to cheese it back. In has so much content that beating the final boss for the first time is considered beating the tutorial.

Also if the some aspects are too bullshit for you there is a variety of mods to fix these, and there is absolutely no shame in using them.

What gets my brain going is actually engaging with the subject. What I mean by that is the following: Let’s say I wanted to further my DnD World. The best way for me to to that is by either playing some myself or sometimes it’s enough to just watch some content related to DnD or Just worldbuilding. I guess what I’m saying is fill the brain with Stuff similar to what you want to do and the desire to do it combined with being already there mentally will do the rest (at least for me)
