I just beat the game. The ending was dumb. It was a very boring cliffhanger. Some weird stuff appears, and you can investigate it...or look up what it means on the Internet. Still boring! Won't be interesting until it comes in game form.

AC's plot was just blah blah blah. I didn't care what the characters had to say unless it was part of the "parallel plot", but most of the information there was read through text, and reading is boring, too.

I say the next game should go sci-fi. Then I'd be more interested. SPOILERS (Like have you play as Desmond with Altair's skills and have it take place in that futuristic city he's stuck in. The Abstergo building looks like it'd be fun to climb! Also...GUNS!)
