Valor & Victory is based on the original tabletop board game and for better or worse is meticulously designed for fans of that format. Those familiar with miniature wargaming are sure to find a game capable of scratching that same itch, but if you prefer your WW2 strategy more accessible, Panzer Corps 2 may be more up your aisle.
The Lizardfolk are a very interesting army to play and the campaign has a lot of character. I personally found them rather weak and relying too heavily on front line cycling for my tastes, but the more I got to explore their strengths, the more fun I had. Overall, if you like Fantasy General 2, you'll probably like Evolution as it mixes it up enough to be fresh, without taking away what makes it a great game.
Emperor sees a lot of changes, both in the DLC and the free patch that accompanies it, but despite all this, many of my underlying complaints with the game persist seven years on. If you’re a fan of the franchise, this patch is one of the best, but it’s probably only worth buying if you’re a central European player.
