3+ years ago and 315 still shows viable tactics to win with core on GoW. Of course today, he would get spanked doing exactly what he did, but fighting off pels with subs, going more cons and using llt to hold isles is still one of the few ways for core to hold arm at bay.
Today there would have been more bombing more destroyers and most likely the use of hlt, but this game was still very fun to watch.
If you want to see where some of the strats for GoW originated watch this game...
