Nice to see that it isn't all bad. Heard some questionable things about it, which was worrying, but the same goes for most portable AC games. :/
It doesn't feel real spin-offy like Bloodlines did, it's an entirely separate story with an entirely new character. There's also a fair share of new mechanics and such unlike Bloodlines which just tried to cram in a few of the main series mechanics.
When I play it I don't feel like I'm fighting with the console's limits either. Like it's dual analogs, 8 face buttons, and two bumpers, and a touchscreen. Everything is mapped well. Also it's a decently sized world that's fairly well populated so it doesn't feel too far from the console versions.
It's just paced and structured a bit differently from all the Asscreed games I've played (all except for 3), otherwise it's Assassin's Creed on-the-go, no limits.
