It's hard to give airbuccaneers a fair review. It really is. Why? Because as of writing, both servers up right now have 0/32 players.
I really doubt anyone will even read this review, only because this is a game time forgot. I bought it when it first came out on steam, and since nothing has changed since other than going free to play (with no bonus for people who previously bought, something that would anger most people but I had my fun with it so I feel it's only fair) all I can do is reminisce on previous times I've played this game in 2013 when it wasn't horribly dead.
I feel like AirBuccaneers is a game that if it had a thriving playerbase it wouldn't be at "mixed" of 60% positive ratings. It's rough around the edges- but not in a way that negatively impacts the game. The game works like most air combat simulators, you fly around in airships and shoot different types of weapons at the enemy while the pilot tries to steer you out of the way of projectiles incoming so you don't horribly crash and burn to your pitiful death. What makes AirBuccaneers different than guns of icarus? Ground combat. It's a lie to say you can walk to your enemies base and kill them via one on one fistfights as the ground is covered in poisonous mushrooms, but in AirBuccaneers you spawn in your home base and can choose what ship to board either by walking onto a docked one or using an hangglider to get to one in the air. But how does this equate into ground combat? You have free movement and aren't locked onto your ship, meaning it's a legitimate strategy to either dismount your hangglider in mid air and jump onto the enemy's ship or to jump from your own and engage in proper swashbuckling- or just take their helm and drive their ship into a cliff. You can also use one of the diverse ship types like the Kamikaze ship that instantly destroys anything when touched (but it horrendously underarmoured) or the massive, immobile fort that has a huge cannon on it but can only move via air maneuver which takes a long time to recharge.
Another great thing about airbuccaneers is the perks and flaws system. I found this very unique at the time, and it still sticks out to me as one of the only multiplayer games that has something like this. There are very overpowered perks in each level progression tree that you can pick to make yourself better suited to one role, but there are negatives in that tree (or other trees) you must choose from as well. This would be just OK if the perks were something generic like "move 10% faster" or "repair 20% slower", but they're all mostly fun stuff like "you're drunk and your screen is tilting", "you don't take fall damage", "you have an eyepatch over half of your screen", and "your gun works like russian roulette and has a random chance of killing you". I didn't get that far in the perk tree as this game died pretty quickly, but it was the main thing that kept me playing and I really wish another multiplayer game would pick up something similar.
So all that positive said, do I recommend AirBuccaneers? Hell yes, if you can find players. It's free to play now, and is a great arcadey game with an interesting character creation system. I just really wish it wasn't dead.
