Do you impulse buy on Steam Sales?Watch
This has stopped my impulse buying. You?
The only PC games I really put any significant time into are Slay the Spire and Rimworld of which both are supported by a plethora of mods so they never get boring.
They always have sales and i wouldn't see the point in just impulsively buying DLC for games I didn't enjoy
I've moved to buying singleplayer games on GOG now since the games are DRM free.
Nowadays you just have to buy the very best. We don't have the time to play and watch every single game, film or TV series that seemed interesting or worth a try.
