It seems X-Wing, TIE Fighter, X-Wing Alliance, and X-Wing Vs TIE Fighter all released on Steam today as well! Looks like the X-Wing and TIE FIghter are the Special Edition versions, not the Collector's Editions that were just added to GoG.
Okay, walk me through this: On GOG - there isn't a listing for the Collector's Editions, just the Special Editions. So I'm taking that to mean if I download the Special Editions, the upgrade to the Collector's Editions will show up later. (if I'm not already downloading them just under the wrong name)
However, on Steam, the versions listed are also the special editions - but those really *are* just the Special Editions, and there is no Collector's edition upgrade coming soon, due to GOG's exclusive deal to offer the collector's editions.
Do I have that right?
edit: Looks like I do - the download came up as Collector's Edition, even if the graphic said Special Edition. All good.
