In this sort of expansion, rather than sequel, Ezio Auditore can recruit his own band of assassins and send them across missions. Rather than just buy in shops, we can invest in it as well. The city of Rome is beautifully pictures & riding on horseback while going through the usual AC stuff feels good. The campaign is solid & engaging for a good 15 hours.
The protagonist is good & that makes for a good expansion arc to Ezio's storyline. With the games how they are going they need to bring a complete change about for the next in series as this game has the right mechanics for success, but needs a consistent change & upgrade to surroundings & lore.
