I started playing Spiral Knights when you could still create accounts from Taiwan while playing through Steam (later on it was no longer possible to make accounts from Taiwan, HK and Macau, because those have their own regional services)
I've played hundreds of hours on my Steam account, have a very friendly guild, even purchased the DLC before it was purchasable with CE...
but the latest Steam update makes it impossible for me to even launch the game, as it was "activated with a product code that is not available in my region"
