That is sad that your unsold game assets aren't burned.
I am not burning any of my card ever!!! i made one by blockanizing it few weeks ago.
A good game economy is Age of Rust.
Yes games need innovations they should not just copy/paste
To make my point about how bad the BCY burn trend is, lets compare the last few months with previous years:
Sept-Oct 2015: 523,000 BCY burned
Oct 2016: 72,000 BCY burned
October 2017: 18,000 BCY burned
Nov 2015: 711,000 burned
Nov 2016: 252,000 burned
Nov 2017: only 33,000 burned
You need to look USD value. Value of token increased in USD in time.
