But if blockland remains at $20 it may be offputting to some users
Oh please.
If that were the case then no one would have ever brought Blockland before.
People don't expect things on Steam to be cheap. The opposite is quite often true.
If someone who uses Steam is too stingy to spend $20 on Blockland then they're simply not going to play it.
They miss out and they were never going to buy the game, whether it was Greenlit or not.
Just because Blockland is an Indie game doesn't mean it should have it's price cut.
That doesn't work with other games.
The price is suitable and fair for a complete game.
I've seen people spend $20 on games in alpha full of bugs.
Blockland is complete enough and provides enough material to be worth it's current price.
It is also much cheaper than any other mainstream game. It is cheap as an indie game. You're not spending $60 on it, like you would from other games from big publishers.
And considering that Steam almost certainly takes a cut from every single purchase, it would be ludicrous for Badspot to cut the price even lower. It's cheap as it is.
