thanks a million for taking time from C2 and C3 dev and answering my question. i went to the site you mentioned and played around with the filters and for desktops (all OS), tablets, etc. the penetration rate was in the mid/high nineties. That's awesome, it appears the folks whose games were having WebGl issues maybe more in luck now and as time marches forward.
the only follow up question i have (forgive me for distracting you from other competing priorities) is this: do these published numbers include US/Western European markets only, or Asia/E. Europe/Latin America? i only ask because C2 via HTML5 breaks international barriers allowing games to be published to a wider audience, but those other markets may be 1 or 2 cycles behind in tech...not sure. just asking.
Thanks a million for all your help.
