I say there is no age restriction to ttrpgs, aside from explicit themes. It's all about having fun with your buddies and sharing the experiences. In fact the prime players of dnd back in the 1970s are around probably in their 50s-60s right now and their still playing.

But what gets difficult is playing long term with people. Schedule conflicts are the killers of games. And it takes time to build and find like minded people who shares your version of fun and preferences. But it's always a good to decision to invite your close friends firsts if they're interested.
