[Feature] Multi-platform games grouping

[krin-san]

Is your feature request related to a problem? Please describe. When game has been released on multiple platforms, it'll be nice to have a way to group or link to game roms from other platforms on the /rom/... page. !532 (in v2.2.1) allows grouping multi-region/-language roms but it only works per platform.

Here's an example for the game Ms. Pac-Man which has been release on dozens of platforms. Romm Search screen find all versions by game title:

but Rom pages only list versions from the same platform:

Describe the solution you'd like Use IGDB "Ports" or MobyGames "Releases" info to cross-reference releases of the same game on different platforms. This info can be used to link games in UI in at least 2 ways:

1. Put other game releases below the game cover art, in the same section where non-interactible "remake" and "expanded" covers appear

   

2. Put other releases into the "Version" drop down, like on the image below

This is now possible with Collections, and we're likely not going to implement this idea seeing as it overlaps with collections.
