XInput VS Steam Database

DirectInput dates back to the Win9x days, and the current implementation dates back to the WinXP days. It's officially deprecated by Microsoft, which basically means "stop using it for new development." Its replacements are XInput (the Xbox controller API) and a similar API called Windows.Gaming.Input, intended for UWP applications. Source: over 1 year ago

Here's how to cure you from your buying habit, checkout https://steamdb.info/, check the price history of the game you're thinking of getting.
