I'm fairly new to Uncharted as a series as I only started playing them this year. Uncharted 2 imo is way easier to play when fighting against higher levels compared to Uncharted 3. However, if you are interested in the co-op of Uncharted, two is dead most of the time.
Yes, it's worth it. There are still plenty of loyalists to U2. I personally didn't enjoy U3 with all the kickbacks and sprinting, etc. U2 is the best multiplayer 3PS I've ever played. I hope Naughty Dog will keep U2MP even though U3 is out. It's a "fresh" change from FPS. Add me if you want. PSN: shotboyz
Yeah I too just got into the series. Even though i thought i would never have interest in this series even though i enjoy the Tomb Raider games from which i have heard this series is inspired by (and the newest Tomb Raider is inspired by this series), I caved in. I just beat Uncharted: Golden Abyss on the PS Vita since it was free. And I just bought off of amazon.com the greatest dual pack for $20.
Question: Do some of the trophies in U2 need to be done online?
