5. The Other Guys Got More Than One
This is the most obvious(and perhaps juvenile) reason on the list: if the other Assassins(Aveline excluded) got more than one game, why can't Connor? Ezio has a total of 3 games(4 if you count Discovery) and Altair 2 - so surely Connor deserves another game, considering he brought more personality than Altair the first time around. Of course there are those saying Altair only had one game, but he was in AC1 and ACR and was playable in both, so he had two games. Revelations also did him justice and gave him enough game time to finish his story properly(and fix that accent). Also, wasn't Ezio's games stretched out more than needed? I mean, it felt like he let Rodrigo live just to set up the next game. Now, of course we couldn't have the Pope dying before his time, so I guess it's fair he got another game, but as far as Revelations, if it didn't have Altair involved it would have been pure, unnecessary filler. Meanwhile, Connor's story could still be explored, including his setting.
