Simply put: Realistic action is FAR more fun in this comparison. Seriously, space ships flying like planes!? No way, I'd go with B5 anytime. If your being chased, no need to do any fancy flying, just turn around while still drifting. It adds new context, strategies, action, and excitement to the battle. I'm planning on making my new storyline follow realism and consistancy while maintaining entertainment. While Star Wars sacrifices realism for entertainment. I don't like that.
In other words: The incredible lack of realism and consitancy in Star Wars bores me.
