8 – Balatro
I wish I could have reviewed the breakout sensation that was Balatro when it originally came out, before taking Steam and pc gaming by storm, because it was one of my favourite games of the year. Despite its looks, Balatro isn’t just poker; it’s a strategic masterpiece where you play ridiculous poker hands, discover game-changing Jokers, and create outrageous, score-multiplying combos all in an attempt to beat the current blind. Every run is a fresh challenge, pushing players to uncover new synergies and break the game’s own rules in the most satisfying ways and overpowered combos possible. Praised for its addictive gameplay loop and innovative take on the strategy roguelike genre, Balatro is a best-selling strategy game and an essential pickup for anyone looking for a highly replayable and endlessly rewarding experience during the Steam Summer Sale 2025.

7 – Victoria 3
Paradox Development Studios Victoria 3 had a rough launch, but a steady stream of updates is proving to be enough to turn it into a captivating grand strategy game and is still topping sales charts while at it. Set during the revolutionary and tumultuous 19th and early 20th centuries time periods, it challenges players to lead their society by tackling societal problems, developing economic policies, and keeping politics in check. Its trump card is its focus on social simulation instead of traditional warfare, making players much more invested in sorting out their problems at home, instead of just playing in an expansionist way. Players must also, as you manage intricate supply chains and economic dependencies, balance the needs of diverse populations, and navigate diplomatic conundrums. Guide any nation from 1836 to 1936, striving for industrial might, social reform, or global dominance. If you love the period, don’t miss the chance to dive into Victoria 3 with its low price of entry of just $15. The Ultimate Bundle is also heavily discounted, at 43% off.
6 – Civilization VI
It’s undeniable that Sid Meier’s Civilization VI stands as a titan among turn-based strategy games, even surpassing the excellent standards set by Civilization IV, one of the best games in the whole series. Civilization VI offers players unparalleled depth as they guide their chosen civilization from the Stone Age to the Information Age. The Civilization formula is well-known to all strategy game players, but if you don’t know about it, it challenges players to expand their empire, advance technology and culture, engage in diplomacy, and wage war to achieve one of several victory conditions, be that conquest, cultural, technological or another one of your choosing. With its unique district system, active research boosts, and dynamic leader agendas, Civ VI is a strategy game classic that’s not only good but one of the best strategy games ever made.
