1. Isaac
2. Spelunky
3. ??? 

I found that to be a charming game and I think that follows the formula. 

The trick is to search your soul and ask yourself whether those games are good because of proc gen or good in spite of proc gen. 

LGR reviews No Man's Sky 

Good games with proc gen -

Nuclear Throne
Super House of Dead Ninjas
Ziggurat
Diablo
Spelunky (already mentioned of course)
Super Hexagon (although the concept is pretty simple)
Teleglitch
Worms 

Minecraft (obvs)
Rogue Legacy
Sublevel Zero
Race the Sun
Megabyte Punch
Downwell
Darkest Dungeon 

Now...

Good 3D current gen first person games with proc gen -

Ziggurat is fps tho. Also Gillard looks promising 

Is Procedural and an excellent game as well.

It's like Isaac but not bloated and broken. 

This discussion boils down to the question:

"Do you like roguelikes?" Yes/No 

Comes to mind as well! 

You need Isaac in your life.

One of Total Biscuit's more annoying videos. 

Enter the Gungeon, I have this. It's ok. The starting guns are lame.

It's all well and good having a game with a billion guns but when you start with a pea shooter every time it gets boring as hell.

I have never really fancied playing Isaac. I probably have it on my steam pile of shame too. 

+ Dwarf Fortress

Otherwise I'm also interested in the way Ultima Ratio Regum is approaching procedural generation. Still waiting for its v0.8 release before trying it. 

Don't forget RimWorld, really good DF-lite with actually usable and nice UI. 

Played it yesterday with friends. It's a really cool game. Dark and creepy, the sound and the atmosphere are very well done. It's most interesting when you are playing with 3 friends with skype or TS, though it's really hard to survive with a team of low level survivors. Playing as killer is fun too, but it looses all its creepy charm then. 

AGONY 

I didn't see much game there. Dark micro-levels drenched in gore, a few things wandering past, and not much else....

2nd worst SSAO ever after Far Cry 3?? 

...looks gorgeous. And scary. That monster at 4'20" seems straight out of a Clive Barker movie. 

If you remember a couple of months ago, GOG inaugurated a service where you can redeem certain games from them if you already own them on Steam. They had a few games up for a while and then the thing went quiet. They just put up a few new games for a duration of a week (6 days remaining as of this writing).

They're the old versions 1 to 3 of Master of Orion, a classic 4X game series. This coincides with the release of the new MoO.

This was just a little heads up in case people followed the service for a while and then gave up. It's looking like the offers are going to be pretty rare and over quickly, making it easy to miss them. But they're still keeping it alive at least.

The last time it got overloaded quickly and took a long time to process some requests. With fewer games on offer this time this probably shouldn't happen.

I'm not at that excited about the new MoO myself. I'll have to check it out some time, because I did love these types of games back in the day. The only thing that'd make me actually excited would be a faithful remake of the old Master of Magic, but that's a pipe dream. And, I guess Civ VI could turn out decent.

It's just a wild guess on my part, but they might make a similar offer for the older games in the Witcher series when this one comes out.
