    Sins of a Solar Empire: Rebellion is one of those games that I keep coming back to years after first playing it. On paper, it sounds like a fairly straightforward space RTS: build your empire, research technologies, expand across planets, build fleets and eventually crush whoever stands in your way. In practice, there is a surprising amount of depth hiding underneath that simple formula. What I love most is the …

    The definitive version of the original Sins of a Solar Empire, so get this instead of Trinity. This expansion adds all kinds of new content, such as minor factions, new planets and ships, random events, and more gameplay variety with different factions. With a solid foundation, the modding community have made this into one of the best space strategy games out there. The best Star Trek mod is Star Trek Armada III, …

    Absolutely recommended. *Sins of a Solar Empire: Rebellion* is one of those rare strategy games that still holds up after hundreds—or thousands—of hours. It blends 4X empire-building with real-time fleet combat in a way that feels massive without becoming overwhelming. The pacing is slower and more deliberate than a typical RTS, but that is part of its strength. Building an economy, expanding across gravity wells, …

    Genuinely one of the best RTS I've ever played, It blends real time strategy into 4x beautifully. There's a certain charm permeating the entire game, whether it's because it's older, or an indie title, or both, I don't know. (I poured 47 hours in it over the course of about 5 days.) That all being said, it's a niche embedded IN a niche, an RTS combined with the 4x genre attracts a certain kind of audience. The kind …

    An outstanding game which is eclipsed in every meaningful way by its sequel, Sins1 / Rebellion still has a few major things going for it. The mods. While ST Armada 4 will (or has, depending on when / if you read this) come out, ST Armada 3 rocks. Ages of the Federation is even better. The numerous sci-fi franchise mods (Star Wars, Battlestar, Babylon 5, more) are bonkers good in terms of visual quality and …

    I bought Sins of a Solar Empire 4 times in total. I own it on disc twice (once as the trilogy and once as rebellion), once on steam and once on GOG. Don't ask why I got the GOG version, I'm still not sure myself. My total playtime since the game came out in 2012 and I got my launch copy is much higher than the 120.4 hours indicated as of my writing this. This game is the apex of the old-school RTS genre, despite its flaws. It's scale is still unmatched by any other strategy game out there and…

    Oldy but very goody - tight, polished, intense wargame. Almost no fluff, yet still enough of strategic and tactical depth to keep the player on edge. One more hidden advantage - it's a very portable game as it runs nearly on everything today, so you one can play it on an office-level laptop when travelling.

    I bought this game in a target in 2008 for $7, back when it was a single CD, since then I hop on it every so often when I want a game to turn my brain off and have passive fun, while SOSE2 is out and many people may prefer the updated graphics and no late game lag, SOSE1 is still a solid game, it also has one of the best modding groups out there who supply mods that make modern RTS games look like a sad joke, if you care about what I have to say then please buy this game it is alot of fun and…

    Wow, talk about memories lol. Sins of a Solar Empire was easily one of the best space-based RTS games of the early 2000s, with Homeworld being the only other real contender, and I've easily sunk hundreds of hours into the series throughout my life. In fact, I think SoSE Trinity was one of the very first physical copy PC games I bought as a kid... simpler times. Anyway, these days you're better off just picking up Sins of a Solar Empire 2 - it's got much better performance, subjectively…

It's straight up better than its sequel, 8/10 game. (Wish the sequel had just refined the downsides of Rebellion instead of ruinining the good things)

    This game is showing its age and not in a good way. I cannot speak for vanilla because I have only ever played modded but I think my issues apply to vanilla, as they apply to the mods. Without Sins of the Prophets this game would have been forgotten to time. This game is not a 4X, as much as it like to pretend its like stellaris, stellaris does everything better. An argument could be made for space combat but its incredibly shallow across all mods. Everything which makes this game a 4X rather…

    I have no idea how long ago I got it for free, but somewhere around 2021, I bought the DLC for it so I could get 100% of the achievements and then left it in my backlog for another five years. I finally got around to playing this game only two days ago. Well, it's a nice strategy game. I expected way less, to be honest. Yeah, it leaves you desiring something more, especially in the diplomacy tab, but then again, the game is old, and I heard the sequel actually improved in that department.…

    I do like this game, however, it can get upsetting at times. The pirates are so freaking annoying. Especially, when the enemy waits until the last second to screw you. Ugh, that can get rough. You can get rid of the Pirates but it feels off when you remove them. I think that should have been thought out a little more. The rest is same ol' same ol' when it comes to games like this. Collect resources, build things, attack the enemy, and so on and so on. This may sound like a negative reveiw, but…
