Yes that is definitely good but in practice 80% of apps contain ads (based on a quick check of the top 20 games I just did) and there's no way to search for only apps without ads.
It would be amazing if there were an app store or curator where you could filter out shovel by criteria. Filtering out "full of pay-walls" and "abuse of in-game currency" doesn't seem possible in Google Play. There are valid games that have ads and value games that accept IAP.
