Played a bunch of SW yesterday. While it certainly does have a lot more code and clips than Batman, it's not nearly as complete as I thought. Lots of bugs and holes in the code that make zero sense or don't have a reason for why things happen. SW is super fast, but holy crap is it obnoxious with dozens of sounds seemingly playing at once and the light shows need a lot of work to make some sense. It's almost like they SW started with damn near everything in the game and they need to scale back and fix a lot and polish. With Batman, we're seeing less, but it's getting polished as we go and not getting anything new until existing code is rounded out.
I'm less impressed with SW code than I was after watching the videos. That said, it's a fun game and I'll dump a ton of quarters into it. However, I wouldn't even consider trading Batman for Star Wars at this time.
