It's true that the game mechanics and engine are showing their age in places. Riding a horse through the Frontier is a constant frustration as it seems to snag on every rock, branch and tuft of flora. Racing through cities on foot can be fraught as well, as the many different contextual actions available through Connor's economical controls - hanging from this, leaping onto that, dodging round this, hiding behind that - overzealously seize power and arrest momentum when it's least convenient. Combat, meanwhile, remains troublingly simplistic: block and counter, block and counter, block and counter.
