> shut their game down around the $200k
Wouldn't upgrading to Pro be a better option? Yearly subscription for a seat seems to be worth about 10k $0.2.
Also you're cost per install is almost certainly going to be significantly below $0.2 because every install outside of:
"United States, Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Japan, Netherlands, New Zealand, Norway, Sweden, Switzerland, South Korea, and the United Kingdom" (I wonder how did they create this list, e.g. Spain and Italy seem to have a comparable or even higher cost-per-click than Sweden , Austria, Finland etc.)
will cost just $0.02
