There's a boatload of difference between the two.
1. There's likely a fuckton more people who own ARK given its low price point.
2. ARK hasn't raised 100 million bucks and gone off the rails from what it originally promised.
3. ARK added everything they really needed to a long time ago already. Had they stopped then and started bug fixing and optimizing the game would be done and people would be happy. They could then add all the crap they want to their hearts content. Instead they've been fucking around with all manner of stuff, added an arena mode and now paid DLC and the game is still an unfinished mess. And now they're probably just going to half ass it so they can call it done and move on.
4. SC on the other hand is more akin to a marketing scam than an actual game being developed. Most of us aren't losing our shit on SC because we weren't dumb enough to give CR dime one to begin with. However that's mitigated by the fact that we were dumb enough to give these dickbags money and no one likes feeling like a sucker, particularly when it comes to money.
