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?
