3 Lines of a Delta

All in one tool to convert various media files. Mp4 to webm, mp3 to ogg, png to webp... you name it. Its ability to convert in batch is the winner.

It can cut down file sizes too. Wish I know about this much sooner. It's free, only need to learn some basic coding to make it function.

FFMPEG

The Ms. Word for coding,

but way better. And free.

VSCode

Good, lightweight app for editing videos.

It's free too.

ShotCut

First game engine I tried. Beginner friendly.

It has well-documented guides. Lots of things can be learned. Free engine anyone can abuse.

Ren'Py

The illustrator go-to software for a reason. The ClipStudio Store has tons of helpful kits, brushes, 3D materials, etc for drawing.

This app can't function without paid version.

ClipStudio Paint

Staple software for architects. 3DWarehouse, its website, has lots of assets that can be used by the users. Highly recommend for those who need some assists for the background.

There are many youtube tutorials on how to render BG from SketchUp. Not sure about the free version but the paid version is great.

SketchUp

Full version seems great.

Otherwise need to use other apps to balance the drawback of limited free features.
