I’ve always been intrigued by Skyfarer - made by FailBetter Games (Fallen London, Sunless Seas, Sunless Skies, Mask of the Rose). It’s a Sunless Skies TTRPG. I haven’t tried it but it definitely seems to fit in the steampunk genre.

I guess that Transformers mobile isn’t coming out then.

While it may not exactly match up with the body of your message, I think this would fit the subject line rather well:

Dwarf Fortress

The Adventurer’s League modules on the DM’s Guild that end in -00 are usually good for introducing people to D&D. They usually have a nice balance of role-play and tactical combat, are low level, and are short or broken down into segments. I personally enjoyed DDAL10-00 Ice Road Trackers. It’s four short 1-hour episodes that can be strung together for a larger story arc.
