That definitely seems an issue with this iteration. Civ V suffered from domination being the tedious victory condition, with excessive unit traffic jams and endless grinds to take cities. It was generally fun to play for other VCs. That's something of the reverse of most Civ titles and Civ VI seems to have gone back to the older model. But science victory - my favourite in most iterations - is tediously slow, culture is likewise just a case of ramping up a certain resource until you somewhat arbitrarily win the game through obscure mechanisms, and diplomatic victory is gone altogether. I haven't had any interest in trying for religious victory, but the apostle interface is terrible and I can't really stomach having to navigate through that for numerous religious units while aiming to spam religion. That leaves treating Civ VI as a wargame, which would be more fulfilling if it wasn't quite so easy. As with Civ V the AI presents a better challenge for peaceful victories than it did in Civ IV or most earlier iterations, but it's the worst yet at either taking or protecting cities. AI wars are endless but almost never seem to result in cities changing hands - there's a definite AI issue there that Civ V largely solved (if only by making more use of ranged units).
