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.
Reviews, worldwide (the counter carries no country): 0/day in the week to Sep 1 → 0.14/day in the week after.
Reviews, worldwide (the counter carries no country): 6.2/day in the week to Jul 17 → 0.14/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 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.

Reviews
I highly recommend this game to all Mecha fans who want to feel the experience of building Robos.
Mechs
jeu amusant et reposant ! pour un fan de model kit gundam je peux dire que c'est plus cosy que dans faire irl XD. Le système de customisation est classique mais apprécier, le jeu facile à jouer et y a un grand nombre de mecha à faire même sans les dlc ! Certe il n'y a pas beaucoup de dlc, et cela ne rajoute pas beaucoup de mecha, mais les mecha dans les dlc sont justes top tier ! de plus le prix du jeu et des dlc sont largement suffisant pour un jeu comme celui là ! je recommande fortement ! j'espère voir plus de dlc pour plus de mecha ^^

No es nada del otro mundo , pero para mi fue muy relajante , si buscas algo para desconectar , puede que este sea tu juego
Really fun and tedious at the same time.
very fun and i would sugest
Relaxante, confortante e muitos robôs. Punho fica doendo de tanto clicar. Vale muito a pena.
2Dロボットプラモデルシミュレーター(パズルゲーム) ランナーからパーツを切って説明書に書かれた完成図を基に色を付けたり組み立てていく。 用意されたデカールを全て貼ったら完成、次のプラモへ ぶっちゃけた話、[spoiler]Last Call BBSに入っていたゲーム[/spoiler]のインスパイア作品 [spoiler]正直、全体的なロボットプラモデルシミュとしての質は向こうの方が高い[/spoiler]と思う こちらは1つ1つのパーツが既に塊になっている、パーツを2つくっつける中が空洞な表現はないし、半円のパーツをはめて輪状にするようなところは無い、(やった範囲では) 一方パーツの色付けが1パーツ単位かつ1クリックで着色できる、その分パーツが多め、着色は楽ではある ランナーも箱のサイズや色別に一気ではなく説明書基準で頭A・腕BCD・足EF・胴体GHIのように1つ1つ独立していて(ストアスクショ参照)、ランナーについていながら既に着色済み(白いランナーに黒いパーツついてることがある)、親切ではあるが雰囲気はあんまり出ていないように思う (後半になると白一色のプラモも出てくるが独立しているのは変わらない模様) 切る演出もゲート(ランナーとパーツをつなぐ細い部分)を切る感じではなく、その手前の伸びているランナーをクリックすると伸びているランナーごと消滅する タイトル画面で飾れるのは良いが、完成品の再編集ができない辺りが少し不親切、 またよく見るとデカールが反映されていないように見える まとめると全体的にプラモデルへの解像度が低い、 ただ一部の仕様を除いてまともに遊べるしデザインはまぁそれっぽい(メダ〇ットやゴ〇ラみたいなのもありましたが) パーツ単位の色付けも楽といえば楽なので初心者向け 私はうーんとなったけどまぁいいんじゃないでしょうか
overall i have had fun with this game the only part i hate are the ai models
Простая игра про сбор моделек и их покрас. Дополнения конечно за денюжку, если хочется побольше моделей. Намного проще и быстрее реальных.
