I think it would be helpful to post links to game-making tools and resources.

An excellent page of game-making programs for DOS is here: https://www.dosgames.com/category/game-creation-systems/

I have NeoBook Pro (registered version). It could make sort-of DOS visual novels or nonlinear ebooks (or an interface for a collection of DOS games or apps), and its registration number is (I think) 1251003HFSMGID

Here is a list of excellent DOS-style tiles, sprites, and other assets that are free to use: https://opengameart.org/content/assets-for-making-dos-games-or-games-like-in-dos-in-the-early-90s

I’ll try to find the links to Adventure Game Toolkit (my favorite) and The Game-Maker (pretty sure it’s on archive.org somewhere)…

The Adventure Game Toolkit: https://www.myabandonware.com/game/adventure-game-toolkit-bk2 or https://archive.org/details/msdos_Adventure_Game_Toolkit_1988

I personally think it’s the best for making text adventures easily (but still feature-rich)!

The Game-Maker allows you to easily make 2-D DOS games. https://archive.org/details/GameMaker_1020

I think these kinda go with it: https://archive.org/details/game-maker_tutor_rsd

Thanks!!! Added those to the mainpage
