Ys Origin is quite possibly my favorite game on Steam.
It might be because I was already a big fan of the Ys series before I played it, but still! It's a great game.
Ys Origin is an action RPG, with a hack and slash styled battle system. There are 3 playable characters, the 3rd being unlocked when you clear the game the first time with either of the first two characters. Each character has a very specific playstyle. To avoid spoilers, I'll only detail the initial two.
Hugo Fact is a ranged caster. He is very powerful, firing off spell bullets from his wand and his twin artifacts known as the "Eyes of Fact" that hover at his side at all times. His is very agile, but he cannot fire while moving.
Yunica Tovah is a melee attacker. Armed with her handaxe (and later greatsword), she excels at close combat. She is very quick, dealing fast, hard damage to her opponents.
When you start the game, you get to choose from many different difficulty settings (Very Easy, Easy, Normal, Hard, Very Hard, Nightmare), as well as choose which character you want to play as. Each character has their own storyline, though all three of them are intertwined. Playing each character is highly recommended, as each storyline offers more and more insight into the overall picture.
Gameplay consists of your typical RPG fare: battling monsters while exploring your surroundings. In Ys Origin, you are tasked with exploring a giant tower that extends to the heavens. The tower is broken up into segments, with each segment offering a different environment to do battle in and explore. They are varied enough to where sometimes you forget you are in a tower and are instead traversing a dungeon located elsewhere. At the end of each segment (and sometimes in the middle) you are presented with a boss. The end of each segment is always a screen-filling boss, and these are the most fun parts of the game, each requiring some strategy to defeat.
The music and sound effects are top-notch. The Ys series is known for their amazing soundtracks, and Origin is no exception. After awhile I found myself whistling along as the music played! You may be inclined to find and purchase the soundtrack online...just a warning! :P
Overall this is just an awesome game. I got it on sale for about $7, but in my opinion the original, full price is WELL worth it. You get a lot of game for the price.
