I just bought this game on demand. This is my first time in the AC series. I like the game very much, I do not however like all the glyph puzzles. They remind me of the old days of gaming when all games seem to have these forums of puzzles.
Yeah there are some annoying things in ACII but honestly it isn't as repetitive as AC1 and gives you a lot more variety of what to do, in terms of side missions and things of that nature. I'm on my second playthrough right now just for fun.
