I am on the free tier, and I'm a novice developer, developing a very small multiplayer game starting with around 10 players and I'm hoping to grow from there. As a result, My server requirements are very minimal, but even with all server settings turned to the minimum (Dasv4 2 cores, 1 standby server, max 1 active server) it seems like my monthly costs will be ~$145/month (2 cores * 31 days * 24 hours = 1488 core hours - 750 free hours = 738 hours * $0.1965/hour = $145). I accidentally left my testing server on and was slapped with a $100 bill right off the bat.
Am I missing something? If not, that is prohibitively expensive, and disappointing from a company that brands itself as being for games of every size.
