本文將描述我們開始開發一款紙牌收集遊戲《Permia – Duels II》的背景和決策制定過程。
《Permia-Duels II》是紙牌收集遊戲《Permia-Duels》的續集。《Permia-Duels》是在2013年發行於Windows平臺上。這款遊戲主要是受到《最終幻想VIII》的迷你遊戲《Triple Triad》的啓發。
我們會發現這是一款非常立基的遊戲。它與休閒益智遊戲《Candy Crush Saga》是截然不同的。然而這款遊戲卻也很容易學習，因爲遊戲的基本規則非常容易理解，遊戲中的紙牌戰鬥雖然很短（遊戲邦注：通常只需要3,4分鐘）但卻能夠提供給玩傢俱有戰術性且有趣的挑戰。
在2015年夏天我們決定在iOS App Store上發行這款遊戲去測試它是否也能在蘋果的平臺上發揮作用。結果證明並非如此。
同時當我們決定開發《Permia-Duels II》（即在2015年11月）時，我們還找不到其它提供了同樣的遊戲深度且具有和我們遊戲相當的戰鬥速度的遊戲。當然了，當Supercell發行《Clash Royale》時所有的這一切就發生了改變。
我們已經使用了像App Annie，Priori Data和Gamerefinery等工具廣泛調查了這個市場，我們的所有發現都證實高質量的紙牌戰鬥遊戲能夠吸引大量的玩家，所以我們的遊戲具有足夠的發展空間。CCG領域還未像城鎮戰鬥遊戲那樣被彼此相似的遊戲所填滿。
Why did we decide to develop Permia – Duels II?
by Jukka Hilvonen
This article describes the background of and our making decision making process on starting the development of collectible-card game Permia – Duels II.
Primary purpose of describing the decision making process is to offer honest self-reflection so that other game developers could possibly learn something from that and advance their own decision making. Secondary purpose is to get feedback from more advanced guys from the industry so that we also could learn and develop our processes.
Permia – Duels II is a sequel to collectible-card game Permia – Duels which was originally published on Windows platform in 2013. The game was inspired by Triple Triad minigame from Final Fantasy VIII.
The short description of the game is that each player has in their hands six cards which are depicted as hexagonal shapes. On each side of the hexagon, there is a number representing the power of that unit on that side. Players place their units in turns to the battlefield. The goal of the battle is to win the opponent by capturing opponents cards. Cards are captured by placing a unit with greater number on the side next to opponent’s card. When all cards are placed on battlefield, the player with more cards on the battlefield is the winner.
As you can see from the short trailer video of the original Permia – Duels below, the game is quite niché. It is far, far away from the casual puzzlers like Candy Crush Saga. Still, the game is quite easy to learn, the basic rules of the game is easy to comprehend and battles are very quick for a card battler (3-4 mins typically) yet offering meaningful tactical brain exercise and the pleasure of occasionally winning fellow players on the other side of the battlefield.
We worked closely with Microsoft during the development and release time of the game via their AppCampus partnership program whose purpose was to get good developers to develop apps and game onto Windows Phone platform. We got ok results from Windows platform due to AppCampus partnership and because at the time there was a lack of good card battlers on the platform and we got nice featuring placements from Microsoft.
On summer 2015, we decided to publish the game on iOS App Store to test out how the game could get a traction on Apple’s platform. It didn’t, as you can see from the chart below.
So why we decided to do a sequel to Permia – Duels?
First, there were few considerable causes which hindered
HTML5 support of animations and other visual stuff
HTML5 isn’t very good tool to present animations, particle effects or other neat visual effects that would allow us to increase visual polish of the game which is required in current mobile gaming landscape. This reduces our chances to get players stick in our game during those important first 10 seconds
HTML5 games performance on iOS and Android
Another big reason is that HTML5 performance on Android and iOS still very very bad, at least on our experience. Sure, Apple’s WKWebView has increased the performance of traditional HTML5 and hybrid apps but that doesn’t translate very well to mobile games where you need to handle a lot of animations, particle effects and real-time counting of these things. This considerably affects our maximum addressable market size which is one of the primary variables which we as a F2P game developer and publisher need to worry about. Even if with such a core gaming experience as Permia – Duels, we still need to make sure that all possible gamers could get to play the game, even theoretically.
Despite poor technical performance, the game was getting traction on key target markets
Third reason why we believe that we have chances with Permia – Duels II is that the original Permia – Duels was doing ok in key target markets in west despite not having good enough animations and poor performance on some of the target devices. By doing ok I mean that it has got decent number of downloads without any paid advertising and also that the retention of the game in target markets (Germany, UK, France) is OK for mid-core game (D1 around 30%, D7: 15% and D30: 5%).
This data tells us that the value-proposition of the game which we describe in the product page is interesting enough for the potential players to download it. Also, the game itself is decent enough (albeit some very clear drawbacks in PD-I) that 5% of all players play the game after 30 days.
The value proposition is still quite unique
The value proposition of Permia – Duels is clear: it offers quick PvP battles combined with meaningful tactical challenges for players. It’s chess on steroids.
At the time when we made the decision to start the development of Permia – Duels II (November 2015) we couldn’t find any other game that would offer same kind of depth combined with the speed of the battles we have. Of course all that changed when Supercell published Clash Royale.
Despite the king of mobile releasing similar game to market before us, we have different enough gaming experience with PD-II that allows to peel decent revenues from the market.
Opportunity is big enough, risks are manageable
We have researched the market space extensively with tools such as App Annie, Priori Data and Gamerefinery and all of our findings confirm that there is enough players for high-quality card-battler games that f2p business model for our game would make sense. CCG space is not (yet) filled up with games that sound and taste similar to each other so that it would hurt the genre overall. I think that has happened in town battler games already.
On the flip side, even if the game would be a total flop, we are able to keep the company alive and survive to fight another battle. Sure, there would be sunk costs and opportunity costs but for us at this time, this the best course of action we could honestly take.(source:gamasutra)
