In one word: browser

The FLOSS version got a bit neglected. At least when I play the paid version in ASCII mode, there are still a lot of graphics in the menu etc. The result is that everything looks different in the menu and in the world.

Games originating in modding communities:

• 0ad
• SpringRTS
• OpenRA (total conversion mods required)
• OpenTTD
• The Dark Mod (Mod for DOOM 3, but is not FPS)

Games that are also sold on app stores, steam etc:

• shattered pixel dungeon
• mindustry
• keeperrl (only ascii version is free and I don’t know how playable it is in that state)

Games that are around for quite some time or gained quite a community around it at some point:

• The Battle of Wesnoth
• Cataclysm: Dark Days Ahead
• BrogueCE (animated ascii graphics)
• Minetest
• Super TuxKart
• Super Tux
• Hedgewars

Open sourced commercial games:

• Castle Doctrine
• Warzone 2100
• Soldat
• Astromenace

Though for those who are more engines (SpringRTS and minetest) the quality really depends on the mods you are playing.

Some stuff I just found and never played myself:

• Catburglar
• Roboden

Open sourced commercial games:

• Charge Kid
• duelyst
• Super Lemonade Factory
• OpenClonk
• Seven Kingdoms

Assets are unfree but freely accessible:

• Cendric2 (nc-nd)
• Star Ruler (nc without music)
• Cart Life (freeware)
• Postal (freeware)
• Pocket Island (nc-sa)
• Strange Adventures in Infinite Space (nc)

I’m not sure about whether these games got 100% FLOSSed or still require bought assets:

• BYTEPATH

A special case because these use CC BY-NC-SA even for source code, which is effectively unfree. They are ports of older Mac games, but most are 3D:

• Mighty Mike
• Cro-Mag Rally
• Bugdom 1
• Bugdom 2
• Billy Frontier
• Nanosaur 1
• Nanosaur 2
• Otto Matic

The “problem” with the open source game landscape is, that a lot of games are either focused on multiplayer or have randomly generated worlds, because that developers can play that too. There are games with single player story line, I think open sourced commercial games are doing a bit better with this. Commercial open source games that are open source from the beginning are a newer development.

I didn’t notice any apps yet and I definitely don’t use any kind of ad blocking.

If the CPUs get strong enough, they could run old raytracing games at some point … especially on hardware platforms that don’t have ray tracing GPUs available for them.

It doesn’t look like that’s open source in any way.

DP also has the DRMs HDCP 2.2 and DisplayPort content protection 1.0

And MPEG LA claims they have patents that are needed to implement the DP standard.

1. TDM doesn’t qualify for the open source definition in the previous post. The assests don’t permit commercial use.
2. I looked at this WAD and it contains .zsc scripts. I couldn’t find any form of license. That means it’s not open source and you are probably not even allowed to redistribute it.

You can’t put TDM and Ashes in a repo of a commercial Linux distribution.

Awesome that this game is back.

They still could be moved to the archive repo
