I was a player on West server that has now quit the game entirely. I have experienced the game from 1-80, and currently have a level 80 character, as long as 60-70 for most other characters. So all of what I have to say is from experience.
Combat is engaging and skillbased.
Engine can be funny at times.
Nexon is a terrible company.
The community is full of trolls and elitists.
Economy fluctuates rapidly without rhyme or reason.
Early-Endgame is intimidating and unrewarding.
Progression becomes incredibly difficult.
Vindictus by definition is a Korean-made Hack 'n' Slash action game, with a choice of 8 current character classes (one upcoming) that each mostly fill a niche in the game as it stands. Storywise? The game is lacking. It's apparent that the voice acting in cutscenes are terribly synced, with zero enthusiasm whatsoever. Not to mention, it barely makes sense, it's tough to relate to any of the characters, and questing/story has devolved into a way to level up faster. As far as mechanics go, the game is amazing. Early on, the game guides you along in combat, but hits a wall in skill requirement once you begin to transition into endgame (Level 60-80). This leads to a challenging, engaging experience, as you require quite a bit of skill, and knowledge of both your character and the boss in order to succeed. Example being the solo videos out there on YouTube, which are quite impressive. Vindictus currently runs on source engine, the physics can be wonky at some times, however. With such things as clipping, or bulging polygons extending throughout the map, or a monster getting launched into space for no reason whatsoever. These can lead to much hilarity. The problems in Vindictus however, are too large for me to be able to enjoy this game anymore.
First off, let's talk about your experience from beginning to end. So you start up Vindictus. 8 characters to choose from, how exciting! Can you change their genders? Though this is something that is common in most MMOs, no. Can I change my appearance? Your options in the beginning are very limited, if you want to change up the look of your character, expect to pay $20 or more on just that. Now let's discuss the balancing of the characters, and the roles they play in Vindictus. Though this topic is very short-lived. The balancing of the game is handled very haphazardly. Currently, Hurk and Kai hold the position of godtier within the game. Where everyone else is disregarded. So if you're looking for stats, choose those two. So you've chosen your character! Time to get into the game! But wait, why don't I have any money? Well, that's because Nexon decided it would be a great idea to gut the early game by preventing gold gains from 1-25. Why? To combat botters. This is concerning however, because the earliest parts of a game are usually the most important to ensure people stay around. Surely the game will pick up right? Correct, the game does end up picking up once you are able to make some money, and have gained a general bit of knowledge about your character. Sadly, this is also when Vindictus transitions into a grindfest. Your experience at this point will consist of rushing through the "storyline", leveling up with barely any money, until you finally hit a brick-wall -- endgame. Endgame in Vindictus is atrocious. If you're not willing to expend any real currency within the level 60-80 range, don't expect to be progressing at all, unless you're incredibly lucky with drops. This is where players frequently quit, if they haven't already in the beginning. As the game becomes frustrating and unrewarding as it attempts to milk you of your money. Upgrades are incredibly hard to come by, and risks can leave you with absolutely nothing. Only the longterm players have stuck around at this point, when the game becomes a social hub for them.
The community itself is terrible. New players on the nexon forums are frequently driven away when attempting to ask questions. Which in itself is filled with trolls, and sarcastic elitists. Don't even get me started on the ingame community. Where if you don't meet the standards of the host, you can be kicked out without hesitation. So yes, the game itself is also filled with elitist jerks. Though it's to be expected out of any game, I have not seen any community similar to Vindictus in this aspect.
Now, let's talk about Nexon. Nexon is notorious for treating its players terribly. Send in a ticket? We'll answer with an automated message then get back to you after a few months. Concern about bugs and patches? There's a chance we'll even consider reading about your concerns, and if we do, it's likely we'll do nothing about it. However, here's a poorly designed event to hopefully make you forget about all of these problems. Updates? Maybe we'll release a bit of content after half a year, of course we won't tell you anything about it. Over my time with Nexon products, I'm ashamed I've stuck around with their games for so long. If Vindictus were to be handed over to another corporation, I'd gladly come back, but the way that Nexon is handling Vindictus is slowly killing the game.
TL;DR Vindictus is slowly dying. Fun for a while, but then you hit a brick wall.
