Leagues of Adventure from Bundle of Holding is for "the Ubiquity-based Victorian steampunk RPG from Triple Ace Games". I have Space: 1889 Ubiquity version. Ubiquity is Attribute + Skill level is number of dice you roll. Every even die roll is one success and you need X number of successes to accomplish your action.

Leagues of Adventure seems to overlap with Space: 1889 although the former is more Earth-based and the latter is mostly on Mars and sometimes other places in the Solar System.

The $27 bundle includes:

Leagues of Adventure ($20, 262 pages)
Weird Science Compendium ($7, 56 pages)
Dramatis Personae ($10, 132 pages) - generic NPCs and henchmen
Globetrotter's Guide to London ($13, 78 pages)

Five adventures is not that much and as I mentioned this setting sort of overlaps with Space: 1889 so I think I'll skip.
