Meta-badges / Quests / Multi-game sets

[oddgoo]

This represents the ability to have a new type of site badge/award that is made up from a variety of simple conditions and achievements from multiple games.
Examples:

So long-a Bowser!
Defeat Bowser in all 5 main-line Super Mario Games

World Tour
Master 1 game in all Retroachievement Systems

Nintendo Hard
Master 45 games for the Nintendo Entertainment System

Sore Thumbs
Get the Street Fighter Achievement and Master 10 other games from the Fighting Collection

There is a related discussion, tho less elaborate and only considers single achievements: #667

This is inspired by the manually managed competitions and other sites like TrueAchievements, but these would be permanent and automatic.

Requirements / Admin

Composing this from an Admin / DEV point of view would be represented by a simple listing of "AND" requirements.
I can see 4 fields for each requirements. Example:

Requirement Type	Identifier	Value	Condition (optional)
Single Achievement	Achievement ID (ex: 8896)	N/A	N/A
Any Achievements from HUB	Collection/HUB Id (eg: 8835)	Number of Achievements to Obtain (eg: 10)	N/A
Any Achievements from System	System ID (eg: 6 )	Number of Achievements to Obtain (eg: 50)	No Hacks/Homebrew

A Meta-badge / Quest would need just 1 requirement minimum, but extra ones could be added and removed.
The badge is of course awarded when all requirements are met.

Requirement Type: Enum / Dropdown
Identifier: Text Field
Value: Enum / Dropdown
Condition 2: Enum / Dropdown

Extra thoughts

Given the Nature of constantly-changing collections, etc. Awards would be awarded on first completion, rather than constantly re-checked (same as current game bades).

For assets, these could give the same type of square awards as events/games, but we can also have a bigger rectangular banner to have a fancier / more distinguishing listing page. Quick example:
