Ohh boy, you know what time it is? It's time for yet another instance of me recommending the same games for 985th times.
Baroque ~Yuganda Mousou~
Currently Roguelike/Roguelite genre is hella popular, and more so than Souls-like during its prime time. But yet I dislike Rogue making me an irregular person, but there's one Rogue that honestly one of the best, especially if you love King's Field (since you ask this question probably not lol), and that is Baroque ~Yuganda Mousou~ (lit. "Baroque ~Distorted Delusion~").
My Quick Summary of Why You Should Play Baroque
Ace Combat 3: Electrosphere
Other people will probably recommend you to start with Ace Combat 0: The Balkan War for its masterpiece of storytelling, characters, and music, and other might go for Ace Combat 7: Unknown Skies (or perhaps the upcoming ACE8). But since we are restricted to PS1, Electrosphere has to take the slot this time around.
But make sure you get the English Patched, since the US release cut several missions and multiple ending.
Front Mission 3
Do you love mecha? Do you intrigue by the SRPG genre? And do your winkle gets hard when there's absolute cheesy build? Then you came to the right place, my friend.
Front Mission 3 will pull with 95% chance of proc where you get hooked by its insane skill activation, and praying for you and your allies to hit the head (you'll understand why when you taste this bad boy). Also Emma best route. Anyone who say otherwise will taste my 6x ROFUP I.
Evil Zone
And to close the final entry for today, I'm going to recommend Evil Zone if want to see one of the more interesting Fighting Game.
Firstly, this game button scheme is beginner-friendly, in fact, "new to FG genre"-friendly as a whole.
And what's make this one interesting is simply because any character you choose to play will have their own canonical story where their fate intertwined with themselves (mirror match stage), with episodic anime style (think of Asura's Wrath) for its story presentation. That's right, not just character ending where you get to see special FMV like in Tekken, but an actual story of why all characters motivated to beat the final boss.
