I can certainly say I'm an example of someone who hasn't bought it because it hasn't been on sale, but 50 dollars for a good game is entirely reasonable anyway and I admit I will probably still buy it one day.
It's funny I came across this thread. Just yesterday I was looking at buying it, but it's 50 AUD. I went to add it to my wishlist to wait for a sale, but it was already there. I realised it must have been on there for a long time.
I was wondering if I somehow missed it going on sale, or it never had.
Yeah, it stings. I did buy 2 copies on launch day for myself and my son (8) though. We have spent a lot of time on Factorio together though and I prefer it much more than Minecraft (although we have probably clocked up many many more hours on that).
