I just got an email that Renowned Explorers is on sale on Steam, 75% off. Great! I'm going to grab it. Then I see that it's got an expansion, More to Explore, which when combined with the base game makes the package only 60% off. Buying the base game alone is a no-brainer, since, at $5.49 Canadian, is the price of a chai latte at Starbucks that I can forego tomorrow. The bundle pops just over $10, coming in at $11.20, so it's crossed over that impulse purchase threshold. Both of these are still great deals, but now I'm wondering: Is the expansion worth it?
