What if you've got half your group that wants to play in a Western setting and another half that wants to play in a Fantasy setting? Well, you compromise and play Outlaws 'n' Owlbears. It's an RPG Zine on Kickstarter now that takes the tropes of the two and mashes them together.
From the campaign:
Outlaws ‘N’ Owlbears takes place in a fantasy wild west that never was. Elementals bound to the hearts steam engines opened the new frontier as train tracks spread across the map. Dangerous creatures and locations dot the rugged landscapes. Sorcerers and wizards claim a nexus of their own to harness the wild magic. Prospectors hunt for rare and exotic materials. Bandits prey on the vulnerable for easy money. Snake oil actually works.
The campaign's about 1/3 of the way to its goal with 13 days left to go.
