So many of us joined SM in different ways, that of finding to word of mouth or some other way. Most likely, most of us, old players, found it online surfing from big game sites. Then we found out it had it's own main site. Then over time word of mouth to phone app.
Now not having adobe, I say there will be less and less new players joining SM. Supermechs does not even make the "top 100" in Google plays store, especially in any category. The only way to come across it in "play store" is with the word "Super" or "mechs." This game will, most likely, be word of mouth now. When people who are just surfing and come across it online, they will see it don't work, then most likely won't waste time playing it, even though there is a downloaded app. This question "How did you Start Playing SuperMechs/come across the game?" will show an understanding if the game needs to be access through online.
