A ways back, I posted on the AC Odyssey thread that I'm at the point where I wish that Ubisoft would put the AC series to bed, and just make unrelated historical titles where you play as an iconic archetype for the time period. This game is just about the epitome of what I was talking about. This game goes beyond being an open-world game set in the Old West to being a straight-up Cowboy Simulator, and I'm loving it.
Now I just need a dozen other games in this vein, in other time periods, where you play as some sort of other historical 'adventurer' archetype. Give me triple-A simulators where you play as a knight errant, and a ronin, a longhunter/frontiersman, a viking, a pirate, and any of the thousands of variations of 'mercenary' that catches a dev's fancy.
I also wouldn't say no to a fantasy game designed like this. A RDR2-style Mage Simulator would be awesome.
