There is now a Wiki entry about Native Americans characters in video games: https://en.wikipedia.org/wiki/Native_Americans_in_popular_culture#Video_games
While this list is far from complete, it is interesting that this topic has garnered an entire entry on its own.
This begs the question, “does a topic become valid once it has a wiki entry?” Perhaps, as it certainly represents at least someone’s interest in posting an entry.
The current / recent trend seems to support this notion as well, as there have been more articles and blog entries about this topic. One could even wonder if this specialized interest is similar to the trend of Native characters becoming “cool” in film (as you know, ‘Indian films’ cycle through as the new Hollywood ‘coolness’ every decade or so…).
Whatever the reason, it is nice to see individuals giving more thought to the Indigenous character, no matter the medium.
