The following files are what I was able to generate:

WARNING
-------
THE FOLLOWING DEMO FILES MAY CONTAIN FLASHING LIGHTS/IMAGES!
THE FOLLOWING DEMO FILES MAY BE UNSTABLE AND CAUSE GAME CRASHES!
USE WITH CAUTION! AND SAVE YOUR WORK!!!


HOW TO VIEW DEMOS:
1. place demo files AND Map folder(s) in your game's root directory
	csgo: steam\steamapps\common\counter strike: global offensive\csgo [YOU MUST OPT IN TO CSGO LEGACY TO VIEW ON SOURCE]
	dod: steam\steamapps\common\Day of Defeat: Source\dod
	ep2: steam\steamapps\common\Half-Life 2\ep2
	hl2: steam\steamapps\common\Half-Life 2\hl2
	sfm: steam\steamapps\common\source filmmaker\game\usermod
	tf2: steam\steamapps\common\Team Fortress 2\tf

2. Launch the game and enable developer console

3. Open the console (~ key) and type
	PLAYDEMO <DEMONAME>
		for example, opening TEAM FORTRESS 2 and typing "playdemo data21' will play the 21st data file in the tf dump


ANOMI'S NOTES:

I haven't had a chance to look at everything yet, but so far my impressions:

CSGO: As expected, lots of broken and crashy demo files, 3 data files
DOD: lots of new weird ones but abt what I expected, just one data map
EP2: more of the same, and 2 very interesting data maps
HL2: same as above but less extreme, seems tame-ish
SFM: Majority are broken or buggy, waste of time
TF2: saw some weird ones, will dive into them later, + I believe data86 was the final demo generated last night
