Summary
Although it’s fairly uncommon for strategy and tactics games to be released on home consoles in the modern day, the original PlayStation had a shocking amount of strategy games available, primarily in the RTS and strategy-RPG genres.
This could arguably be attributed to the immense popularity of RTS gamesthroughout the 90s, during which the PlayStation was one of the biggest home consoles available. However, due to their age and common dependence on the player’s familiarity with the genre, many strategy games for the PS1 can be brutally difficult.

This popular standalone expansion for the originalCommand & Conquergame isn’t as brutally difficult as other PS1 strategy games, but as an older RTS game, it can be extremely unforgiving in some of its latter missions.
Command & Conquer: Red Alertis an addictive and highly polished RTS game, and its dual campaigns certainly help to keep players engaged, but it can be a challenge to reach the end of either campaign, especially when playing on the PlayStation without the use of a mouse.

5Front Mission 2
This turn-based tacticalmech strategy gameis the second entry in the popularFront Missionseries. Although it could be argued thatFront Mission 3is a superior entry in the series,Front Mission 2is debatably the most difficult due to its often complex mechanics and inaccessible systems.
Front Mission 2, like the otherFront Missiongames, is relatively complex; the game has more weapon variety than the first game, a system for terrain that affects the accuracy of mechs and ammunition. Although the otherFront Missiongames may have some of the hardest missions,Front Mission 2is arguably the most consistently difficult of the games.

Set in the iconicWarhammeruniverse,Warhammer: Shadow of the Horned Ratis an often overlooked entry in the abundance ofWarhammervideo games due to its age, but it’s a surprisingly punishing and tactical retroWarhammerstrategy game.
Warhammer: Dark Omenmay be an arguably superior game in its design, accessibility, and visual style, butShadow Of The Horned Ratremains a solid strategy game nonetheless, andits complex systemsand difficult missions make it one of the most hardcore experiences on the PS1.

Centered around managingthe jobs and abilities of a broad ensemble of characters,Final Fantasy Tacticsis a tremendously difficult and strategically deepturn-based tactics gamethat maintains a fast pace.
Much of the difficulty inFinal Fantasy Tacticscomes from the customization of characters, tasking players with coming up with good strategies and efficient builds in order to make the most out of each character.Final Fantasy Tacticsalso features a lot of difficult battles; however, this difficulty can, unfortunately, be mitigated through early-game grinding. Despite this, players going into the game with no prior knowledge are almost sure to have a challenging experience.

This deep and highly complex tactical mech strategy game was arguably one of the most complex and inaccessible experiences to be released on the original PlayStation. The game’s user interface is enough to give any regular gamer a mild headache, but its robot-wars-style auto-battler combat was way ahead of its time.
Carnage Heart’s difficulty mainly comes down to its steep learning curve and complex systems. InCarnage Heart, players must build artificial intelligence for their hulking mech soldiers, essentially creating a program that tells them how to fight. On top of this,Carnage Heartcontains elements of resource management, adding an extra layer of depth and difficulty even outside of the game’s highly tactical combat system.
