I absolutely, 100% recommend this game. Be warned, however, this game is NOT for everyone.
A lot of people call this "mindless hack and slash gameplay". They're really not correct in this judgement, and are, in fact, being pretty ignorant towards the series.
First and foremost, let's address the combat. I believe there are 83 characters in this game. Each character can carry two weapons. For the first weapon, you ALWAYS want to have their 'Ex' weapon equipped. This is the weapon they perform the best with, and gives you access to special attacks, called 'musous'. With these weapons, you will have better attack power, better combos, better everything. So with one of these weapons per character, it in turn translates to 83 UNIQUE MOVESETS IN HE GAME. Of course, you can equip any weapon you'd like as your second weapon, so go crazy!
Weapons also come in many different forms. I believe there are 6 different ranks of weapon, measured in stars or dots. This determines both the rarity of the weapon and how powerful they are. 6th tier weapons were added in Xtreme Legends; before this edition you could only go up to 5th level weapons. There are a ton of weapons in this game, so if you like weapons, this game's got it. Additionally, each weapon has 1 of 3 'affinities'; heaven, earth, or man. This is basically a rock, paper, scissors type deal. You want to have a weapon equipped that is strong or equal against the opposing officer's. That's why you have two different weapons; both having a different affinity so you'll NEVER be at a disadvantage.
Like I said before, there are a lot of unique movesets and warriors in the game. This keeps the combat fresh, with all the combos you'll be able to pull of and special attacks to try out. On the harder difficulties, you CANNOT just mash buttons and hope to survive. This is why I absolutely hate when people call this game a "button masher". There is legitimate strategy and skill to this game once you put enough time to access the hgher difficulty tiers.
The actual gameplay revolves around a battlefield each time. Think of it sort of as a third-person real-time combat strategy game. There are different strongholds or forts scattered across the map. If you defeat the officer inside of that fort, you'll capture it, and your soldiers will spawn there. This is how you gain more troops to overcome the opposing army you're fighting. Then, you have more powerful officers of the opposing army you have to take down, and various other objectives to complete. These all happen in real-time, so pay attention to your map in order to know what your current objective is.
There's also a ton of content in this game. There's your basic story mode which has SIX different storylines to play. Each storyline additionally has extra, "What-if" scenario stages that really add to the replayability of the game. That's not all, though! There's free mode, which let's you play as any character in any story. Mostly used for levelling up, still nice.
Then there's ambition mode. This is completely new to Dynasty Warriors and is really quite huge. You're goal is to rebuild this little town. You fight consecutive battles without dying, and the further you get, the more rewards you're given. You colelct materials to level up the town and the various buildings in it, and weapons to level up your warrior and suit him up for battle. It's really unique and I highly recommend giving it a try.
After that, there's challenge mode. You use stock characters to complete various arcade-style challenges. A fun way to test your skill.
So, given all this content, it will honestly last you a couple hundred hours if you plan to 100% it. And no, none of what I said included ANY DLC. That is COMPLETELY OPTIONAL and not needed. I know the base game is still expensive, so I wanted to make sure I addressed this. I still do not have any of the DLC and this game is still wonderful and amazing. I really hope more people give this game a shot and enter the wonderful world of Dynasty Warriors.
