Artifact - Skill Rating, Leveling, and Balance

Posted: 20 Dec 2018 05:39 PM PST

Today's Build Your Legend Update focuses on skill rating, account leveling, and card balance.

Skill Rating and Account Leveling

This update introduces independent skill ratings for constructed and draft games. It also includes an account leveling system that tracks your overall experience with the game and allows you to unlock level icons and a set number of tickets and packs. More information on both systems is available on the update page and the patch notes below.

Card Balance

A common pattern in physical card games is to design around the goal of never changing cards, and to only make card changes or bans in extremely rare cases. Our initial approach to the game was to follow this type of methodology and keep balancing changes as a last resort, in large part because we thought players valued immutability very highly.

Since the release of Artifact, there have been a lot of discussions surrounding this topic. Input came in many forms, some from online discussions, some from direct feedback with players, and some through discussions among our own team members. This caused us to take a step back and spend a bunch of time debating the merits of the different arguments presented.

In the end, we struggled to see the benefits of immutability outweighing the numerous downsides. The average player mainly wants the game quality to be high above all other considerations. Players who focus a lot on deck building would prefer a more diverse and engaging meta to play around. While some card collectors enjoy having a small number of really valuable cards, many others are happier in a world where the full set value isn't overly dominated by one or two cards.

Further consideration also made us realize it was the wrong approach from the development side. An extremely high bar for making iterations will indirectly cause future set development to be worse off. Long term set creativity will suffer if we are reluctant to try new ideas because of fears around not being able to make adjustments.

Our conclusion was that embracing ongoing card balance for a digital game has a lot more upsides for the game as a whole. Once we shifted over to this new mindset, it became obvious to us that it was a more natural fit with how we tend to develop games. Starting with today's update, we will be taking an incremental approach to balancing, with the primary goal being to improve the gameplay quality over time. New set expansions will undoubtedly cause bigger meta shifts, but we'll use incremental balancing between sets as a way to make sure that gameplay quality is as good as it can be.

We think player activity and demand is by far the biggest factor for overall card value, so we expect this to be a net positive for everyone over the long term. We also believe the marketplace remains valuable as a whole, as some changes will cause some cards to go down in value and indirectly cause other cards to go up. However, we realize that some players had a different expectation when buying from the marketplace, and so as a result we'll allow a one time buyback exception for the next two weeks. Any player that previously purchased today's changed cards from the marketplace can now visit this link to learn how to sell the cards directly back to us for what their peak selling price was in the 24 hours prior to this announcement. This sell back process will begin tomorrow, Dec 21st.
