There is a lot of good things in Reincarnation, but the AI and map progression issues have not been resolved from the previous versions.
-Fun races, lots of units, nice strategic approach.
-Graphically appealing, while not being demanding. Well Optimized. (Not last gen tough).
-Good Campaign Storyline.
-Almost no bugs or glitches (so far).
-Leveling system is addictive and dynamic. Can have different builds.
-Horrible AI. Seriosuly.
-Strategic approach is fine, execution is terrible. Weird and unfair issues with CPU enemies.
-Extremely slow paced gameplay.
-Difficulty is based 100% in the raw power of the enemy armies and it scales poorly as the game goes on.
-Once behind it's almost impossible to recover.
Now, explaining with more detail:
1.- Disciples is a franchise that relies heavily into the management of the encounters you have. The main strategy of the matches rely heavily in how you develop your troops WITHOUT DYING, mainly because the game punishes you hard if you loose a leveled squad. In the past, this kind of difficulty was appealing, but by today standards, it's just not well implemented.
The game is more about choosing the right targets to level up and not about the strategic combat. This means that the difficulty is developed by the way you approach the leveling and not about the challenge of battling or developing the resources.
2.- The AI is just broken.
During the map phase, all the enemy armies just clean the mobs and level up in a certain rate, making few mistakes, while you need to see your way trough the random neutral troops that can range from easy to impossible. While the idea of having a linear leveling experience is boring, making you roam the map searching for the right mobs seems hardly an improvement. This is worsened by the fact that you can't afford to loose a single troop from the squad, so you will be repeating certain battles just for the sake of keeping the squad alive and not loose time in healing (wich, too, can be punishing in certain situations). And you can add to this the fact that while you loose time choosing targets, the AI already knew the right path so now it's 3 levels abobe you and still power-clearing camps.
In combat is worse. Melees will approach to engage, ranged will target the nearest high priority target (weakest).
No much variation there. All the difficulty relies in you having to clear the lesser troops because usually the neutral enemies will have an outstanding threat that you need to carefully engage if you don't want to get one-shotted. And that is all. It's an easy clean or a fight you will have to repeat until the mobs behave the way you needed or until certain platforms that give you power spawn in better positions for you (wich ends up being the only strategy that the field of battle provides and that is completely random. The AI will rarely use them well).
-While fun and useful when you level and clear the map, spells are rather secondary. They can be extremely necesary in certain maps that have incredible neutral camps difficulties; and be just a fun thing to do in other scenarios.
Don't get me wrong with this review. Reincarnation is still a good game. It pretty much is a revamp of disciples 2 with a new combat system that is not really that cool. But i can hardly recommend it with all the issues it haves. Gaming has gone a long way from the games that had broken gameplay and weird AI issues. D3 should have been the improvement in those departments and not just the downfall because they not only couldn't fix them but maked them worse.
There were other minor issues, but i settled with the most important in my opinion. To do this review i waited to play enough time, but now I felt like I was ready to give an honest, objective opinion about the game.
