I have expected this earlier, imagine steam taking Bitcoins cost higher than average game, yet no quick solution. This is sad news to steam, with those higher fees, which merchant will be happy to use Bitcoin as a payment method? None! I particularly will not try it, would rather continue to keep or hold my bitcoin. 
Just wait for the lightning network (and read about it). There are serious testing going on on the mainnet too, but you have to wait for it. It will solve the fee and the speed problem, but the project needs time to get fully tested and working. What I'm waiting for is some merchants to test it (maybe in online webshops) because the more testers are joining the project, the sooner we'll have the solution delivered. So the solution is arriving but don't hold your breath.... It's better to implement something later then to implement it sooner with bugs still in the system...The reason steam stopped accepting bitcoin is because people must have complained to them because they had to pay a fee again to resent their payment because they never spent enough the first time and the price of the fee and the fact it was so volatile made it hard to justify a $40 game when you paying $12-$16 fee.
