Also, I'm not sure if /u/Wilnyl has seen this one, but it's pretty much Accurate Battle Simulator written all over it.

I use this one. Just save the size you want (I choose the largest one) somewhere you can find it easily. I use an icon folder within my downloads folder. Then right click on your Clustertruck folder on your desktop.
Properties > Customize > Change Icon > Browse > [Location where you saved the .ico] > Open > OK > Apply > OK.
If it doesn't change right away, you can reboot Windows Manager or your whole system and the changes should take affect then.
This is on Windows 8 and I'm pretty sure it only works for folders, not .exe files or shortcuts.
Then why not avoid searching for games on the actual play store/ios store yourself and use a curated list to look for them? Curated is pretty fucking good at filtering crap stuff.
