Use hours as default playtime unit instead of dd:hh:mm

It would look more clear with hours as default playtime unit in my opinion. It's also a more wanted variable than dd:hh:mm

I feel like this was discussed before but I can neither remember nor find it. I personally prefer the current way that shows days as that's easier to comprehend than some big number.

Same as closed issue #3969. Not sure if it is concerning.

This is a personal preference thing and there are people on both sides wanting opposite things.

The only real way to "fix" this is by providing a toggle that allows a user to switch between which they personally see.

I did a twitter poll about this last week and 75% of users preferred to use hours rather than days
that said it should be taken with a grain of salt since it's only 50 people and a twitter vote

My opinion is that I also prefer using hours as a measure because most other gaming platforms such as steam use hours as a measure for play time. It makes it easier to get an idea of how much time I've been playing, rather than seeing an arbitrary number of days that has no meaning to me.
