It might be worth noting that nowadays both Ys: Oath in Felghana and Ys Origin are available on Steam.
Being the indie wonk that I am on some days, there are more than a few things that I'd like to speak up on. the first being the output of one Daniel Remar, most notably Iji and Hero Core.
Iji itself is something of a side-scrolling action game, with a fairly in-depth character customization system for a game of it's type, as well as a graphical style that's rather reminiscent of games like Flashback and Out of This World. however, perhaps the most unique aspect of the game is that pacifist is as equally rewarding and interesting a mode of play as full-on murdermode, in that the content of the story, dialogue, and even the heroine's own pool of voice quotes change depending on which road you decide take your gaming style. The final boss battle is so amazing, that Dan had to write an entirely new rendering program just to handle it.
The second is Hero Core, which is quite a fun little action-exploring game, which also has its own little quirks, such as the fact that you have access to the final boss fairly early on, and he is quite beatable if you're good enough at the game- there are just a number of hoops you have to jump through for the best ending.
Beyond that, however, there are some others. While La-Mulana is a bit better known on the internet, it's still a bit of an obscure game- which is a shame, as while rather hard, the recent remake of the game is probably one of the best metroidvania-style games ever made, built on the sheer awesome of its soundtrack and atmosphere.
Oh yeah, if all of you are still looking to scratch an old PC gaming itch, there's always gog.com.
