It's tentative, but we are planning to have a boxed version of Rebellion when it's released.
Thanks for the info, even if its tentative. Also, I know its been awhile since I originally posted, a big thank you Ryat and Annatar11 for the information about Impulse archives. I didn't know about that. Thanks!
I can't wait for Rebellion. I remember when I first found out about Soase. I preordered my copy, loaded up the Beta (I started when Beta 2 was out), and started to figure the game out fairly quickly. An hour or two into it, I told my sister's boyfriend who was visiting at the time to take a look at it, and began trying to convince him to preorder it. He said he didn't have enough money to pay for his bills and the game, so I gave him the money to put into his account the following day. He preordered, and, when he loaded up the Beta the following day, called and said it was the best gift I ever gave him (however, if memory serves me correctly, it may have been the only gift I ever gave him). We both ordered the collector's box set.
I was hooked on the game in the first hour. Prior to Soase, my favorite space RTS game was Conquest: Frontier Wars and had been for the nearly 10 years it had been out. I had played Homeworld 2 and Nexus: The Jupiter Incident (not sure I would call that an RTS, maybe a tactical game), but Soase was the first game to come out since that I enjoyed more. Not only was the game itself great, but the included manual was full of enough information and backstory about the factions, ships, etc. to almost be its own strategy guide. At least it was way more than I've come to expect with a game nowadays.
During the Beta, I was astonished how much the developers listened to the players and their suggestions. This was my first game from Stardock/Ironclad, having dismissed GalCiv1 and 2 for being turn-based. As I was playing the Beta and later the full game, I began to look into Stardock's games and bought GalCiv2, learning how mistaken I was to ignore it. Now, my top favorite games are all made by Stardock/Ironclad (the only exception being World in Conflict). So not only was Soase a great game, it also introduced me to other great games.
I'll still be on the lookout for more info on the retail version. Maybe my earlier suggestions will be useful as to make it more cost effective. Its also nice to know that I can make my own physical copy later on as well. Thanks again to all who took the time to answer my questions.
