I picked up FFXIII at launch and I only put about 15 hours into it. I loved the Paradigm Shift battle system. I found it very fun and fast-paced, but the story just didn't pull me in, and the linear style didn't match with my old-world expectations from RPGs. I still want to put in the extra time to get passed that "20 hour" demo period, but we'll see.
I wanted to try FFXIV from the get-go, but the tragic launch waylayed that. I'm anxious to see what A Realm Reborn brings to the table.
Excellent retrospective. Don't listen to the anonymous trolls in the other posts.
