First up, if you exchanged argents for cash in Skyforge, you're going to get a refund if you did it during a time the system was broken. Which is a great thing that this was addressed so quickly:

Earlier today the team noticed the Argent to Credit exchange rate, which automatically adjusts based on player demand, had its minimum exchange rate set too low. As a result, players were receiving too few credits for each Argent converted than originally intended. This issue has since been corrected - bringing the exchange rate back up to a minimum of 160 credits per Argent.

As compensation, players who converted Argents for less than 160 credits will soon find the credit difference deposited into their account in order to ensure they have the correct balance based on the correct exchange rates

We apologize for any inconvenience this may have caused and thank the community for their continued feedback and suggestions which help us improve Skyforge!

Additionally, the producer posted a letter welcoming players to early access, if you wish to read it for the feels.

If you didn't buy a founder's pack, early access key giveaways have popped up online. I didn't find any active, but if I do I'll share the link around, assuming they'll stay active for long.

Players have found that if you purchase any amount of argents, you'll receive additional content. This may or may not be a bug, but assuming it's not, you can get a cool headstart if you don't have the founder's pack.

I've been playing it all day today and a good bit of yesterday, though honestly I've spent a lot of it fooling around with the U.I., but I do find the game to be a lot of fun. If you're not a founder yet, then next week you'll be able to play for free. I hope to see you in the game!
