hmm Demigod seems to have phrases like 'MOAB' and 'Persistent Online World' all over it so I left it off - added the others though, thanks!

I put it because it did say single-player in the supported modes, but you could say it's an afterthought.

Changed the intro blurb with your suggestion - thanks to both of you!

A reminder to put a Bethesda section. Let me help you a bit:

Brink
Delta V
Dishonored
Echelon
Gromada
Heretic/HeXen series
Hunted: The Demon's Forge
Magic & Mayhem
Prey
Rage
Rogue Warrior
Symbiocom
Wolfenstein series
XCar: Experimental Racing
Zero Critical

Updated Ubisoft for the release of World in Conflict

Not sure if I should be able to add Mad Max to WB - looks like they were only the distributors of the film in some territories so I'm not sure if it counts as their own IP...

Getting to Bethesda - under Z for Zenimax to confuse everyone!

Moved Noctropolis from EA to Night Dive as they just released it on Steam...

You haven't removed the game from Ubisoft's section yet.

Corrected, thanks

OK finally processed these and updated the Zenimax section, that made my job very easy so thanks for that!
Brink seems very multi-player focused but ended up including it anyway
Eshelon had a sequel Published by Encore, which is part of the same group as Viva these days, by the look of it so actually added it to Viva instead
Also moved Commander Keen from Apogee / 3d Realms to Zenimax too

*edit* Actually Echelon is even odder than that, the entry now reads "Echelon universe (Bethesda - Encore / Viva) (although Operation: Matriarchy is Buka / 1C) "

You should remove the series from your list, as the first one was released on GOG on 24 March, published by Black Forest Games (a company comprised of members from the original developers of the game, Spellbound Entertainment), instead of Viva Media. Don't forget to edit your timeline to reflect the game's addition here.

Also, another game that isn't in your Focus Home Interactive section, is Styx: Master of Shadows.

This should be removed, as the first game was released on 23 July (you even indicate as such in your timeline). The first game was released on 23 October 2014, published not by Paradox, but by its developers, Battlegoat Studios. You may want to edit your timeline as well.

Edit: On second thought, Supreme Ruler was released here before Paradox came, so there is no edit the timeline.

This can be removed.

It's here now.

While that would seem an accurate guess overall, I'm kinda skeptical about whether CyClones and Necrodome really belong to Ubisoft. While Ubisoft did buy SSI, it seems that the rights to their games were all over the place, with some purchased by Ubisoft (like Panzer General) and others by The Learning Company (The Forgotten Realms games). This might also be the case with the other games that GOG has self-published (Fantasy General, Pacific General and the Warhammer games).

Honestly? I'll start believing that it could be possible when Activision decides to start rereleasing their games here. In one month, we'll have exactly 3 years since their last release here (Spycraft).
