5 Sim Games To Buy in Simfest Steam Sale 2025
1. Rimworld

If you ever wanted to micromanage people at the edge of space, then RimWorld is for you. RimWorld simulates the story of a group of survivors on a planet far from home. Its most interesting gameplay mechanic is an AI storyteller that personalizes your experience as you play. The storyteller you pick at the beginning will have you deal with cataclysmic events and space pirates, with DLC content adding more variation to the same.

However, RimWorld dives deeper with colonist traits and backstories and simulates the survival of an entire colony. You will explore the procedurally generated planet for resources and ways to increase the population of your colony, all while dealing with various events that will either wipe out your colony or leave you barely hanging on.
Rimworld is available on Steam for the Simfest Steam Sale 2025 at a discounted price of $27.99 (-20%)
2. Frostpunk 2

A direct sequel to the first game, Frostpunk 2 as a city-builder simulation, offers more intensity and story than simply placing buildings and calling it a day. The sequel gives you more scale, more events, and politics. You are the steward appointed after the death of the previous captain of the city and must take accountability for thousands of lives, desperately trying to survive the harsh winter. Frostpunk 2’s scale will have you questioning the life of your gaming setup, as the game becomes incredibly process-heavy later on.
Frostpunk 2 will make you sweat, managing resources, overpopulation, and moral decisions that make you act for the entirety of the city. On top of all that, you will have to submit to the council as well. The council is a new mechanic introduced in the sequel to make things more interesting. Before you can pass any law in the game, the council has to approve it. This leads to negotiations about your policies that might affect other decisions in the future of your city.
Other than that, you will also meet different factions that may or may not align with your interests. You will have to juggle the internal and external state of your city to make it through the apocalypse in Frostpunk 2.
Frostpunk 2 is currently available at the Simfest Steam Sale 2025 for $29.24 (-35%)
3. Manor Lords

Become a medieval lord and conquer your territory in a one-man developer game, Manor Lords. Meant to be a spiritual successor to Banished, Manor Lords adds more combat options to this medieval city-builder game and has received massive success. Set in 14th-century Franconia, Manor Lords is incredibly realistic in its lore and in-game events that follow. Think Crusader Kings-level realism.
The game’s success can be credited to its in-depth city building, real-time battles, incredible graphics on UE5, and socio-economic simulations.
Manor Lords’ lack of story content, however, keeps it grounded as a city-building simulator. However, you can adjust many settings in-game to simulate any type of medieval scenario you want to play. There are RTS elements to the game as well, with different lords presenting a significant challenge to conquer and claim territory. Manor Lords has become a classic in the simulation genre, and its lack of story content should not stop you from enjoying what is essentially a very deep city-building game.
Manor Lords is available for purchase during the Simfest Steam Sale 2025 for $39.99(-35%)
4. House Flipper 2

For certain players, becoming a house flipper is pretty fun. Take this fun to the next level and you get House Flipper 2. With an entire sandbox mode and new game mechanics, House Flipper 2 has become a relatively successful game compared to its prequel. In House Flipper 2, you flip houses, renovate or redesign homes, and make them brand new for your clients. Who knew cleaning and repairing an entire home could be this fun?
Following the previous game’s massive success, House Flipper 2 is created on an entirely new engine, meaning improved graphics and more flexibility in game mechanics. This is especially visible in its sandbox mode, where players can design entire houses in different locations in the town of Pinnacove. There is also a story mode for this game, where you simply renovate or redesign an already existing house according to your client’s needs.
House Flipper 2 is known for its grounded graphics and its gameplay loop that just involves cleaning and decorating houses—plus its own lore that you can discover between the walls. The DLCs add more lore and equipment for those who loved the original, along with a free DLC for co-op play.
House Flipper 2 is available during the Simfest Steam Sale 2025 for $25.99(-35%)
5. Empires of the Undergrowth

Ants have fascinated humans for their unified behavior patterns for eternity. Empires of the Undergrowth gives you the ant-colony RTS game with simulation elements. Manage multiple ant species, manipulate their DNA to create mutants, and grow your colonies to their full potential. Face deadly enemies and rival ant colonies as you fight for survival and dominance.
Empires of the Undergrowth lets you dig inside the earth and ensure the survival of your colony. It also has a story mode where you control a genetic ant colony in a documentary-style narrative that takes place both underground and above ground.
Empires of the Undergrowth has largely flown under the radar, but it is a fun RTS/simulation game to enjoy—especially if you like insects. Deploy raiding parties, manage your brood, and learn how your ants survive in harsh nature. There are two modes for the game currently: a story mode and a sandbox mode where you can adjust various settings to your liking.
Empires of the Undergrowth can be purchased for $29.99 currently.
