Can you add Romancing SaGa 3 (HD) on Switch Asia (physical) ?
Thanks in advance.

@everyone - Those have all been added, except for Romancing SaGa 3. Does anyone know if that's a remake or is just a cleaned up version for modern systems? I have no problem adding the Switch release on the existing entry, just want to make sure it's not a brand new game that should be standalone.

Tales From Off-Peak City Vol. 1
https://cosmoddd.itch.io/tales-from-off-peak-city

Atari Flashback classiscs: vol 3

I've added a bunch of the requested items, but I'm a bit backlogged on compilations at the moment. I've been looking into the various D&D titles and I think we need to change the existing entries. Here's what I'm thinking:

• Baldur's Gate: Enhanced Edition - Needs to be a compilation of Baldur's Gate and Tales of the Sword Coast.
• Baldur's Gate II: Enhanced Edition - Needs to be a compilation of Baldur's Gate II: Shadows of Amn and Throne of Bhaal.
• Icewind Dale: Enhanced Edition - Needs to be a compilation of Icewind Dale, Heart of Winter, and Trials of the Luremaster.
• Neverwinter Nights: Enhanced Edition - Already set up as a compilation with the base game and its various expansions.

Once those are configured, there are a couple of combo packs from 2019. Completionator does not support "compilations-in-compilations", so these would include the child games instead the Enhanced Edition entries, like so:

• Planescape: Torment: Enhanced Edition / Icewind Dale: Enhanced Edition - Needs to be a compilation of Planescape: Torment, Icewind Dale, Heart of Winter, and Trials of the Luremaster.
• Baldur's Gate and Baldur's Gate II: Enhanced Editions - Needs to be a compilation of Baldur's Gate, Tales of the Sword Coast, Baldur's Gate II, Throne of Bhaal, AND Siege of Dragonspear (which was apparently included in this.)

Any thoughts on this? Have I missed anything?

Not related to the D&D games but i've found
Countdown The Game - DS

@moho_00 - those categorizations of the D&D games work, certainly, and looks complete! Siege of Dragonspear was indeed included in the BGI/BGII compilation.

Also, please add World of Horror for Steam.
