No one expected this game to work, and everyone thought an epic flop was brewing over at Ubisoft. How do you take single player stealth assassin gameplay and tack on multiplayer to it? Somehow it worked, and while the experience isn't quite the crazy wild west of say something like GTA 5 multiplayer, it definitely had solid appeal as you wondered whether the person next to you was a simple peasant... or an assassin with a blade ready. Honestly, it's still fun today, if you can find enough people for a match, that is.
On the single player front, exploring Renaissance-era Rome (a much larger city than the previous games) while battling the corrupt Borgias family was quite satisfying, and adding in the ability to recruit followers added a welcome new dimension. Being an assassin is a good time, but leading a whole cabal of assassins is even more so.
