So yeah. I figured we could use a list like this somewhere, as we have a thread for free games but it doesn't seem to focus on RPGs, nor does it recognize RPGs out there that aren't so free, so here it is. I'll update it as I remember more but at this very moment, this was all I could remember. Right now, I've intentionally left out Amaranth and Aldorlea games since there are a lot of each of them.

Still trying to decide what all qualifies for the list, also, so if you want to contend anything I add to the list, by all means, feel free.

N/A means I couldn't find/didn't know/wasn't sure of the information at the exact time of writing. If you DO know the information, and it's not there, let me know and I'll fix it.

Everything on this list is playable. That was one of the requirements.

I am very strictly trying to stay away from roguelikes and Diablo-likes in this list.

Everything is in alphabetical order.

End of list.

You should add this. ;)
Doom & Destiny

I did something similar back in 2011 with the Recommended Indie Games and Where to Buy Them thread, but I didn't get the feeling that there was much interest in such a project and I guess it was mostly helpful for myself only. Anyway, feel free to browse the list, there might be a few indie RPGs in my old list that you didn't mention yet.

Yeah, looks like I missed a few.

Also, side-note: very strictly trying to stay away from roguelikes and Diablo-likes. Done.

Also added Cardhalia.

You should probably print that in bold letters on top of the list, instead of adding it as a sidenote in a post here, as I bet there are lots of players who wouldn't immediately agree that they are to be excluded from a list with RPG in the name. The definition of "RPG" is a quite controversial topic, especially amongst those who think it isn't. ;)

There's the obscure indie RPG DBQuest. The game's about 20 years old. It's very similar to the Ultima titles circa IV and V. The developer seems to be (gradually) working on a remake or spiritual successor.

Also check out the RPG section of the Freeware thread, e.g. Dark Disciples.

Done.

Also added:
- Teudogar.
- Darghul Classic.

Can't believe I forgot those.

Playable. It just needs an obtainable, playable version somewhere.

EDIT: For instance, Dragon Alpha was completed and on sale for a while but it's completely disappeared from the internet other than its Macgamefiles entry, so I wouldn't add that since you can't play it.

EDIT2: Added:
- Enhanced Newcomer.

And fixed Nethergate being ahead of NEO Scavenger.

Added:
- Terra Aegrus ( http://www.youtube.com/watch?v=guy8vY2IImI ).
- Terra Aegrus II: Rise of the Lich King ( http://www.youtube.com/watch?v=ZJoXqtmb5AY ).

Haven't played them yet myself, but I wanted to leave the note that the videos make them look much better than the screenshots do at first glance (for one, check out the battle system).

I'd support bringing some of these good, older titles here (if GOG can convince the pubs to lower the prices to 5.99 on some of the non-bundles.)

At least link to the [url=http://www.amaranthia.com/modules/oledrion/category.php?cat_cid=1]lists for both.

Anyway, I'd recommend:

Unepic
Recettear

GOG should really get both

I'd like Grandia 2 to come to GOG even if it was a horrible port
