I thought the first had a good story, nice graphics, and I liked the climb on anything platforming a lot. That said, a few things ruined the game for me (aka, I'd never replay it.)
1. Beggar ladies.
2. Those dudes who push you.
3. Timed missions
4. Unintuitive (IMO) sword combat.
Still, in spite of what my first comment may suggest, I am hyped for the sequel. Worst case scenario, the interesting story gets expanded on. Best case scenario, they also manage to bring the gameplay up a few notches.
