I played AC2 without playing AC1 and enjoyed it immensely. I couldn't stand the dynamic shadows in AC1 (yeah, that's the initial reason I didn't play it

). Then I was told AC1 gets very repetitive so I didn't really care about not playing it. Tried it again recently and just can't push myself to play it.
Now, AC2 was simply amazing! I enjoyed the story very much. The whole templar/assassin conflict, the history of man and all the other connected things were done in a superb way. The way it was presented was incredible. The part I enjoyed the most was "The Truth". Though Ezio's story was nice too.
Now, I read through the AC1 wiki and frankly, I didn't miss much. So I'd say drop AC1 and dive immediately into AC2
