I genuinely thought this 2 hour limit was for just customizing the mods - no, it's a 2 hour limit on gameplay modding per day. Which, for an app that's supposed to help you play "your games, your rules" seems to have changed your policy to "your games, your rules, so long as you pay us money!"
This annoys me. I've already been starting to search for games based on what games you added mods to, but if this is the way you're going to be doing things moving forward, I'll have to switch to other mods that don't just cut me off after 2 hours daily.
