Gameloft does support it's newer releases, even it's to "adjust" the game balance, but you're omitting most of Gameloft's catalog, mainly the older games, which they do not support. For example; you mention Dungeon Hunter 4, but omit the first 3 games of the series. The first two games (which also happen to be pure premium) haven't been updated since 2010, and the 3rd game was last updated in 2012. Those games seem abandoned to me. Hardly prolific.
