Anuto TD (found a few days ago, isn't super feature rich but still fun to kill time)
Mindustry (never played a game like it before, ended up supporting by buying it on Steam)
Supertuxkart (I love how many custom add-on karts and tracks I have)
For non-games:
Termux (allows me to get apk files and install Revancify for add free yt)
VLC (I don't mind slow updates and have yet to switch mostly because I can't find anything better that isn't more complicated than it needs to be and/or is closed source)
KDE Connect (I have almost always had problems with moving files from and to my desktop via cord)
I'd include something like Linux, but I personally feel that's kinda cheating because of how large it is compared to the others.
Have not heard of those two. Also, I personally wouldn't be able to add cuberite since I quit mc after the whole chat reporting thing and have yet to look back.
I'll definitely have to look into Beyond All Reason, though.
Edit: Looked up BAR and my computer would go nuclear on me if I tried it considering the website for the game lists a minimum requirement of 16gb RAM and mine only has 16gb installed with 13gb available. My computer would melt in a matter of just trying to launch it, probably.
