Prices
The United States storefront in every case, so this compares stores and not countries.
Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Every market we collect.
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Aug 4 → 0.29/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Несмотря на довольно простой геймплей, Sigma Theory умеет увлечь. Игра цепляет атмосферой холодной войны, интригами и сложными моральными выборами. Отличный вариант для любителей глобальных шпионских стратегий.
TL;DR. Don't ever buy this game for its $18. If you REALLY want to try it out, you should get it at least 70% off. A scientist in my team decided to indulge in a side project to induce sapience in animals. She came back a few days later having died and uploaded her brain into a dog, which could be sent out as the best agent in the game. Another scientist came to me and demanded she get her performance heroin back. I picked the option to tell her if it's so good with enhancing performance, she should share it with the science team. She went "hell yeah" and ended up overdosing herself and a different scientist to death and instantly researched multi-dimensional gate. I sent a korean hacker to Russia so that her international hacking activities wouldn't trace back to my country. I noticed both russian scientists were bisexual and ordered her to seduce them. So she became permanently stationed in Russia keeping watch on her polycule and deleting arrest warrants in Britain, which in my mind she's doing it while sipping coffee in Star Coffee shops. (Starbucks pulled out of Russia in 2022, fun fact) This sounds incredibly fun! So why am I not recommending this game? This game is shallow as a puddle and wide as a puddle, and the puddle shrinks! In this game, you win by monopolizing the scientists using agents. Agents have 2 numerical stats (Intelligence and Strength), and traits which most gives bonuses to actions and some bypasses checks or hinders. You lose if the other AI finishes Sigma project first, there's too much global instability and nuclear war happens, or your government loses faith in you and pull funding. As the game goes on, countries drop out the Sigma and become inactive on map. I completed 3 games in 7 hours, and I am pretty sure I already did all the interesting strategies in this game. It's the same thing: acquire scientists, and stop other countries from stealing them. There are just two ways you get scientists: you either exfiltrate them out or buy them off through diplomacy. And defending your scientists is trivially easy. "But what about different builds?", you might ask. The countries have different bonuses that are trivially different. Agents? There are only two stats that ranges from 1-8. It can throw me dozens of "unique" agents, but you can only have so much variety. The traits mainly help with exfiltration, which is a series of RNG events you can't really plan for. I don't like exfiltration, which is a problem because it's a major part of the game. The only thing you're doing is you're throwing an agent in that you hope has enough positive traits to get you through. "But what about the world-altering Sigma technologies? Surely they shake things up!" Biggest disappointment, the answer is an emphatic NO. They hype up the impact of these technologies with quotes and character dialogues of them being shocked, but mechanically their impact is really lame. Most of them are just, "more health", or "+1 to a stat". You perfected cloning, so now you have a couple agents that can't die, but you have to be really dumb to get your agents killed. You can access parallel dimension, which gives 1 agent access to gate, which only thing it does is halve exfiltration so it's just not as obnoxious. The vast majority of the dialogue options and scenario text you are required to read to pick the correct option are so cookie cutter that my mind just eventually glazed over them. There are some exceptions, like the stories I laid out to you, but they are the very few exceptions. The characters and agents don't feel like real people because all their dialogues are copy-pasted. The Spouse is so unimportant that it's mind-boggling why it was included. The grave accusation that I will levy against this game is that it is nowhere as interesting as it [i]imagines[/i] itself to be. I'm happy I only paid 6 bucks for this.

Everything fails. Is your guy 7+ intelligence? Guess what?! He can't hack anything. Is your guy 6+ strength? Guess what?! Can't extract anyone. Anything happens and the governments panic. Do nothing.....same outcome.
easy to learn, fun to play
Immersif, complexe et difficile en fin de partie. Mais tellement passionnant !!!
多少年了我也要把这个游戏拉出来给个差评,游戏内容极少,妻子几乎毫无作用,莫名其妙成功莫名其妙被翻盘,角色的特点毫无意义,是我玩过最差的游戏
iyi
Oyun genel olarak güzel bir oyun ve ara ara dönüp kendini oynattıran bir havası var. Basit bir şekilde mouse ile oynamakla birlikte kendi içindeki seçimleri, ajan alımları, farklı ülkeler ile kim daha önce araştırmayı bulacak rekabetlerini tatlı buldum. Lakin oyun bir yerden sonra aşırı tekrar ve pek fazla bir şey sunmuyor. Uzun saatlerinizi verip oynayacağınız bir oyun değil Sigma Theory. Lakin arada sırada kafa dağıtmak amaçlı farklı bir temada bir oyun oynamak istiyorsanız ideal. Bana göre potansiyel vaat eden oyunlardan bir tanesi eğer daha fazla geliştirilseydi. Lakin şu anki haliyle de oynanır ama tavsiyem indirim zamanlarında oyunu almanız
Very boring, not enjoyable.
