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 Aug 31 → 0/day in the week after.
Reviews, worldwide (the counter carries no country): 0/day in the week to Jul 21 → 0.4/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 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.

add cloud saves and I'll change this to a positive. happened with the first game I'd uninstall and then go back when DLC came out and no cloud saves so had to restart every time. this time I've had a system wipe and if I was to reinstall I'd have to start again. pretty basic requirement for a steam game these days.
Pretty alright. Gunpla sim. No AI disclaimer unlike the 2d version. Worth checking out.

good to play while waiting for a model kit to deliver
[h1]5/10.[/h1]
As a builder... eh it is ♥♥♥♥. Have to make in specific order. Can not put all parts together like arm to torso until the end after you made all the parts. Can't stop making a kit... you have to finish it in the first go. Can't save and come back later. Can't stop and go do another kit and complete later. Have to sit down and do kit from start to finish For the price and limited options to play such games and most most importantly for having the damn decency to toss in a few waifu bots I make this a recommend.
Gunpla almaya paranız yetmiyor ancak yine de hevesinizi bir şekilde gidermek mi istiyorsunuz ? İşte Mech Builder 3D imdadınıza yetişiyor. Gerçek Gunpla yapma deneyimine olabildiğince yakın olan ve kütüphanesinde oldukça fazla maket bulunan bu oyunda arkanıza yaslanıp uygun bir ücret karşılığında Gunpla yapmanın tadını çıkarabilirsiniz. Üstelik yaptığınız maketleri istediğiniz gibi boyayabilir ve pozlayabilirsiniz. Çok zorlayıcı ve karmaşık bir oyun olmasa da gayet eğlenceli diyebilirim.
Очень чилловый симулятор сборки модели, надо наконец свою уже закончить в самом деле
Sensacional o jogo
It's so relazxing, a great way to experince the joy of building gunplay and mecha plus it's a WAY cheaper option.
