Look up diminishing returns. That's exactly what we're currently dealing with. The difference between 6500 and 65000 polygons isn't as noticeable as the difference between 6500 and 650.

Meanwhile, an AC-type game is focusing its budget more on adding more to the world than beefing up graphics.
You should check out my YouTube channel, The Golden Bolt! I review all types of video games, both classic and modern, and I also give short flyover reviews of the free games each month on PlayStation Plus to tell you if they're worth downloading. After all, the games may be free, but your time is valuable!
