You should play it again, especially if you’ve played the FS2 campaign before, since you’ll notice what’s different even more. Just the functioning TAG missiles are worth the price of admission. But actually good versions of Slaying Ravana, High Noon, and Their Finest Hour? Sekhmets flyable in Bearbaiting? Actually good Prometheus R? Fast Boanerges? Fighter-bomber Bakha? It’s definitely worth your time.
