I think the ritual spell casting works in Tabletop because the DM has better control of time so the 10 minute ritual casting happens when the DM wants it to.
This is a case where CRPG and Tabletop are different enough that I would vote no ritual spells in CRPG because you just can't make them work right. I mean, do you have a ritual take 10 minutes of real time to cast one? how do you balance rituals so they don't become free spell slots?
I would just make it that out of combat, you can cast ritual spells without spending a slot. They’re not really spam-worthy spells anyway like cantrips. And it’s not like you have to wait one hour in realtime for short rests either.
