If the % of rev from online gaming decreased then it is not necessarily saying the sector is not booming. The mix of revenue and the %'s of each sector changes as a result of many factors
1)Higher revenue from other sectors
2) Loss of customers (hence revenue) from online gaming
3)Decline in revenue by the exxisting gaming companies.
4) All the above.

any/all of the above could be the reason for the deecline in the % of revenue from gaming. Very different to a decline in Revenue from that sector.

I dont know which of the above is the reason and neither do you. Irrelevant really. If you want an answer why not ring the company!
