He's right.

AC went downhill fast after 2. Brotherhood was bearable, but the 2 after that... lawl. It's annualized now and they're just greedy fool.s It's in the same boat as CoD at this point. Way overhyped each year, and needs to just go away and stop being milked.
I agree. I loved ACII and got every achievement (non-DLC). Brotherhood was pretty good, and Revelations was mediocre. I beat ACIII, but it just didn't have that something that wanted me to play it badly.
Also, I did update the original post, but it's likely I missed quite a few games. Feel free to add suggestions.
