I've played Vindictus since the start of OBT. I've played the game for many hours throughout these few years, and I must say that this game is by far the most addictive game I've ever come across with.
With that said, here are my pros and cons.
Hack and Slash - This game is unique in game-play with it's hack and slash mechanics. I have played many hack and slash games, and I can say none of them compete well with Vindictus. It's battle system has kept me playing for years. It's combos gave me a rush of dopamine from the get-go. I got hooked, and it felt good.
Character Diversity - Each character has it's unique play-style. Currently, you can play as 8 characters. Lann, Fiona, Evie, Karok, Kai, Vella, Hurk, Lynn, and soon Arisha. Each character is unique in battle. Even while Vella and Lann share the same weapon (Twin Swords), they feel very much different from one another. I've tried each character, and can see similarities among them, but they stand out on their own.
The Abundance of Channels - Each Server has a total of 200 channels. Whether you want to interact, or play alone, channels provide a spot for everyone.
The Story - The story is beautiful. I will not explain it, I don't like giving story spoilers. I will say, this game would be an amazing anime.
RNG - Of course, this will be my first con to list. The RNG (Random Number Generator) of this game is very broken. You want to gear up, and enhance as best as you can?
Gear enhancement can be very, very risky.
After +6, you will risk the enhancement to 0, and after +8, you risk breaking.
Some people have a lot of luck, and could possibly go from +0 to +15 in one go, but that's extremely rare.
A lot of players resort to buying NX to buy Enhancement Runes to protect their arsenal.
Over all, the RNG seems really unfair to everyone.
Drop Rate - This goes along with the RNG. The drop rate sucks in this game, even with VIP, or VVIP services (which range from 10$ to 20$ a month) most of the drops end up being garbage.
Server Stability - (Peer to Peer) - More times than not, I stay away from 24-man raids, and leave boats where the host only has 1 bar. Peer to Peer works great in Korea, but face it... North America is much more vast than South Korea.
Bots - This game is infested with bots. These bots also inflate the economy, making things harder to earn.
Depot Shop/Avatar Shop Pricing - The prices tend to be high up there. Though, you do not have to buy anything from these shops, people prefer to buy to look good, or gear up better. The game can have it's ugly pay2win moments.
Recycled Dungeons - Perilous Ruins, Ruins of Sanctity, and Hilder Forest are the same maps. After a while, everything looks familiar, and dull. Prairie Entrance and Fomorian Base are purposely the same location. (Fobellow Prairie). That includes Ainle, and The Catacombs. (Night time, and Day time)
Community - The community of this game can either be amazingly awesome, or terribly annoying.
It ranges from down to earth people who actually play this game, to sorry people who try to tell you how to play the game, and act like they are a better person than you based on their numbers. Though, this is in every game, it's something one must learn to endure in MMORPGs.
Server Stability: 5/10
Premium Shops: 6/10
Overall Rating: 6/10.
NOTE: Despite of my review and rating, I recommend this game. You should try it for yourself before you make any conclusions.
