Overall, my reaction to Flames of Vengeance was about the same as my reaction to Ego Draconis. I thought the quests were fun, and I enjoyed hunting around for hidden buttons and secret rooms, but the combat was sort of a drag, and the fights (even the end boss fight) provided no challenge whatsoever. If you still haven't played Ego Draconis, then my recommendation is easy -- go ahead and buy The Dragon Knight Saga because the games are entertaining enough, and the bundle makes them a bargain. But if you played Ego Draconis before, then things are a bit tougher. Do you spend twice as much money for a bundle that will invalidate your saved games, or save money and perhaps never see some of the gameplay improvements? Perhaps the best course of action is simply to wait until Larian releases the promised patch to update Ego Draconis to the new engine or until the bundle drops to a price that's more accommodating to your wallet.
