Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Every market we collect.
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.

Add-ons
Each DLC is estimated with the same model as a game, then summed — a modeled figure, not reported DLC sales.
Updates
Build ids and update times come straight from Steam's PICS — the same source SteamDB reads. Patch history grows as we record new builds.

เกมเพลย์ไม่เว่อร์วังอะไรมาก แต่แต่งหุ่นได้คุ้ม
雖然沒什麼故事可言,戰鬥也不算賣點之一, 但如果高度喜歡自己拼裝機械人及武器,這遊戲就會十分有趣,但首要是透過戰鬥去收集素材。
咱先不说中文翻译有问题了,等了将近一年你就更新了音乐包?画的大饼也没有实现,游戏只有一个人形骨架。 战斗做的一坨,刷零件也是非常耗时无趣。 开发团队疑似跑路。 不推荐购买。

This and every other Pro feature is free until October 20, 2026. A free account is all it takes.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,515 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

I can make gundam, it's good.
I love the customization and the combat system isn't hard to learn and get used to either! The graphics are easy on the eyes.
