This has been said before but FFXVs soundtrack is great, but its implementation poo. All the best tracks are barely heard, and instead we have to deal with harmonica trash all the time XD
Sadly true for many parts of the game. This perfect imperfection is what breaks this game for many. They do something awesome and break it down by doing something stupid. This goes through the whole concept of the game.
Great action based battlesystem with fancy moves - Bad enemy design that makes most oft the battle system irrelevant or not fitting because to chaotic
Friend Commands to utilize your teams strength during battle - Useless cutscene that removes control from the player and makes the battle less dynamic during these attacks
Friend Attacks that do much damage and look really good at times - randomly executed when attacked from behind instead of giving the player more control
Skilltree system to develop your character during your journey - Only minor differences and way to expensive skills for near to no value in the game
Big open world with some really nice scenery - Some paths are blocked by invisible walls
New Items and interesting HP system during battle - Item menu pauses game and breaks the flow of the battle, also exploitable
Game focusing on companions with unique bonds between them - Dumb as shit and die every 10 seconds (except gladdydaddy, he still runs into everything but has 10 billion HP on level 1)
Hunting system with many special creatures to hunt - No variation in battle except a nice monster model, also the hunting system is wasting time for no reason. Why only allow to accept one hunt at a time is beyond me
Great Photo Feature by prompto which also adds a bit to the actual story - causes your save file to go over 600mb of file size if you save many pictures.
Chocobo riding is fun as hell - Stupid senseless renting and change of controls for no reason during rides. Picking up items while on the chocobo is not possible.
Flying car is amazing - Only way to die in this game
The list goes on and on
