That would be pointless to contact them over that game collection as both Atari and Digital Eclipse have confirmed in statements the dlcs are not coming to GOG at all sighting' 'technical issues '' and that they won't do anything about that nor do they have any plans to bring here the '' Expanded Edition'' that has the dlcs built in that version of ''Atari 50'' at all..

Worse still its a pattern with Digital Eclipse sighting the same problem with any game they are involved in here so far be it lack of updates or no DLCs coming as being' 'Technical issues'' In fact it seems like the only reason we had got one complete product they was involved in was Disney stepping in over the ''Disney collection '' of them basically forcing there hand to get the complete version on here when Digital Eclipse tried to pull the same stunt there .. It also seems like the Tetris game collection is headed in the same pattern as pretty much all other Digital Eclipse involved game scenerios we have on Gog so far

But ya Digital Eclipse basically seems to use Gog as a way to get double dippers on drmed storefronts as they clearly don't care about Drm-free storefronts by the track record any other storefront thats drmed they update and add dlcs proper

So ya

I suggest to focus first on their old games with low profile and good ratings. I would like Aliens vs. Predator and Vanquish. Some games from the Total War franchise would be possible too. Finally, I mention Bayonetta and Binary Domain expecting longer times for they. Perseverance prevails, patience will warm even a cold stone~

the Phantasy Star series

Ecco the Dolphin!

Is Persona really published by Sega? I would much rather have it's series from which Persona is a spinoff, Shin Megami Tensei. I wanna kill God using pokemons.

AFAIK, yes, both SMT and Persona are developed by Atlus and published by SEGA.
and agree, SMT would be fantastic, too. how could I furget...

Sonic Heroes and Sonic Riders. Both games already have native PC ports, but were never released on digital platforms.

I would like to see Anarchy Reigns and Fist of The North Star : Lost Paradise on GOG as they are simply awesome in terms of pure action and chaos !

My absolute favourites are:

Medieval 2: Total War
Empre: Total War
Company of Heroes

Billy Hatcher has a pc port

I would kill to see the arcade version of galaxy force 2

and lets not forget.
Alien Soldier

Rome Total War
Medieval Total War
Shogun Total War
Medieval II Total War
Shining Force series

+1! ^_^

Panzer Dragoon Saga: https://www.gog.com/dreamlist/game/panzer-dragoon-saga
No need for remake, simply remaster, scale up properly and port to PC.
Please do not mix it up with the cheap Panzer Dragon 1 remake (which is available on GOG). It is the best in the entire series and probably so special, there is no second game which is equal to this, it is just a own game in any aspect... anyway, i mean the RPG in the series, just as i named it. If GOG gets it... well, a milestone reached on a Sega game on PC. It could probably be scaled up 16:9 the easy way. However, porting it is probably difficult because... it is not the only game with this issue... the source code is probably lost.

Ah yes, it can be gotten on Ebay, it is almost free: https://www.ebay.com/p/5682?iid=156495239615

Skies of Arcadia: https://www.gog.com/dreamlist/game/skies-of-arcadia-2000
No port available but probably easy port (the Dreamcast had a good Windows compatibility). Surely great game and well known. As far as i remember it was my last Sega game short time before the Dreamcast "died". Sega was releasing this game on the Gamecube after... i got me both games on both systems. Although, there can never be to much versions of it, a PC port is basically "the final cut" if done well. The game is good as it is, simply need a port and remaster.

There are a lot of other great games, sure, the list would be big. But to me it is important that a "true heritage" is arriving on PC and still realistic bringing it over.

If those old jewels are still to difficult... simply continuing the Yakuza series (which is native on PC... close to no work at all, but nothing a true Sega lover would feel excited about). I guess it was going fine so far, yet it is not the most legendary Sega game.

Nah, they probably almost got bankrupt after releasing it and every time they hear that name they feel a pretty cold breeze.
Guess the DLCs are made for the DRMed platforms. That way nobody outside those "premium platforms" will ever get their bonus content, or so i heard... according to a fairy tale i almost forgot already.
"SNK 40th Anniversary Collection" seems to be alright, i did not hear any GOG user moaning about missing content. SNK is better than Atari, anyway... Atari is a big name but i would play SNK way sooner than that.

Just to make you smile: Even on Steam "Atari 50 collection" is incomplete because they had to remove Warbirds from Lynx by a day one patch... so, complete is not the exact word.
