If anyone's been following it more closely than I...
Is Don't Starve's Reign of Giants DLC worth the measely 10% discount for $4.50?
It sounds like there's a decent chunk of new content, and I know it's recent, but I'm a cheap motherfucker who's cheap, and hesitate to buy "expansions" for the same money I bought the base game for.
Eh. If you haven't played Don't Starve to death already it might be worth it. From what I've seen it doesn't add much new gameplay, just more content and crafting and critters and difficulty. The core gameplay is still "Gather resources, build stuff, gather more resources, keep going until you gain self sustainability, get bored, die, repeat."
Like, I accumulated 94 hours of Don't Starve before getting bored and uninstalling it. Then I got the DLC during the Summer Sale when it was cheaper. Reinstalled, played for about half an hour, got bored again, remembered why I lost interest in the game before, stopped playing. Personally I just played the game to death.
That being said, if you still like the game and have the money, and want some new content, go for it, I guess. Could wait until another sale or deal or something if you want to save more money.
