A few years back, when I only bought stuff from Games Workshop, I learnt about a game called Warmachine that existed, but wasn't produced by Games Workshop. Teenage me then went and bought more Space Marines, deciding that since it wasn't GW, it wouldn't be worth it as people around me didn't play. Plus, at the time, nothing screamed out to my "ooh shiny" syndrome and demanded purchasing.
Fast forward a few years and I became aware of the Retribution of Scyrah faction. Part of me went "oh cool, elves. I like elves." Another part of me said "I have nobody to play against, and they would take away spending from my armies I could be playing. I'll pass."
Zip forward through time to the present day and I'm getting ready to eat my words.
