Loved the agent recruitment feature in Sigma Theory. The ability to customize their skills and backgrounds adds a nice layer of strategy to the game. I've spent hours recruiting and upgrading my team!

This game is an absolute train wreck. The UI is clunky, the gameplay is slow, and the AI is broken. I'd love to give it a higher rating if they fixed these issues - until then, nope.

Not too shabby for a game in this genre, but it feels a bit incomplete. The AI agents are a bit too predictable and some of the missions are a bit too easy. Hoping for more updates!

Loving the mod support in Sigma Theory - it's been great to experiment with different game mechanics and difficulty levels. One thing I'd like to see is more community-driven mod creations - would love to see user-generated scenarios!

This game is insane! I've spent hours just setting up my spy network and trying to outmaneuver the opposing faction. The mod options are a great addition, but I wish they were better organized.

Overall, I'm thoroughly enjoying Sigma Theory, but I think the game needs more variety in terms of missions and objectives. A bit more diversity in the types of missions would make the game feel more dynamic.

The UI in Sigma Theory could be improved - some of the menus are a bit cluttered and hard to navigate. But overall, I love the game's premise and the mod options make it really engaging.

Sigma Theory has a great 'what-if' scenario aspect to it - I love replaying missions with different choices and seeing how the world changes. One thing though, I wish there was a way to save and load individual missions.
