CnC_Remastered_Collection VS VVVVVV

That's just a clone game though. And the originals were actually made open source with the release of the remaster.

Not most, but quite a few legendary ones were released in a "source available engine, paid maps" kind of way. Check out Id Software's github for a couple versions of DOOM, Quake and Wolfenstein. EA has released Command & Conquer's source code (here).

You could just look through the source code and see if you can spot anything though.

If anyone curious about some historic examples here is the pathfinding code from the C&C/Red Alert games

>The path algorithm works by following a LOS path to the target. If it collides with an impassable spot, it uses an Edge following routine to get around it. The edge follower moves along the edge in a clockwise or counter clockwise fashion until finding the destination spot. The destination is determined by Find_Path. It is the first passable that can be reached (so it will handle the doughnut case, where there is a passable in the center of an unreachable area).

That being said bespoke development being done badly is the source of horror stories. It's like old games C++ being notoriously "horrible garbage hacks" and yet, code like this or this is very well documented and not bad.

What do you more than this? https://github.com/electronicarts/CnC_Remastered_Collection

I merged the upstream branch of the source code into my mod branch, did a new build, moved teh required files into the mod folder and confirmed the mod worked locally.

The source is wrapped up in DLLs so it can run in their frontend, but all of the old game source is there: https://github.com/electronicarts/CnC_Remastered_Collection

As a specific example, the code for the Command & Conquer video games was released by Electronic Arts awhile back. Looking at some of the code for C&C: Red Alert (https://github.com/electronicarts/CnC_Remastered_Collection/tree/master/REDALERT), I was struck by how many comments were included. For example, this is a snippet from one of the source files (HOUSE.CPP):

VVVVVV at least has since become open source.

VVVVVV - A platformer where you flip gravity instead of jumping. Was recently open-sourced to celebrate the game's 10th anniversary!

Yeah, just look at this beauty! https://github.com/TerryCavanagh/VVVVVV/blob/master/desktop_version/src/Game.cpp

Finally, games are really that complex. Check out for example Terry Cavanagh's blog post on releasing the source code for VVVVVV, and check out the source for Game.cpp (although keep in mind this was ported from ActionScript).

So it seems to be an unofficial policy rather than a written rule, if those allegations are true (remember that those are Wolfire's claims of what Valve said). Certainly there doesn't seem to be consistent enforcement - for instance Tales of Maj'Eyal is free, but $7 on Steam. Apparently there are some minor differences - does that mean that they can claim that it's a "separate version" and hence doesn't need price parity, even though 99.9% of the game is identical? There's also VVVVVV, which is open source (albeit years after initial commercial release) where you can freely build the exact same copy as on Steam ($5), including steamworks support. Does that count as a "separate version" when you just have to compile code? Admittedly these are two indie games, albeit extremely well-known ones, but then - isn't Wolfire Games also an indie studio?

I think it's worth noting VVVVVV has actually been open-sourced https://github.com/TerryCavanagh/VVVVVV
