I will freely admit to not knowing that assets in the game were AI based upon purchasing the game. However, I must say that for what I brought the game for, the game has proven to be rather relaxing and stress-free, which is what I had hoped for. The gameplay loop is easy enough to pick up, and can quickly be mastered; nothing is too difficult in the game, which given its aim is to be relaxing is good. The graphics are good enough, though I consider the colour palette a little too bubblegum like for my tastes. My major criticism of the game so far has been that it only has one soundtrack (unless I missed something) - while relaxing and enjoyable enough for the first 20-30 minutes, it has become quickly repetitive since. I understand one of the main criticisms from several reviewers has been the repetitive gameplay loop, to which I would respond by asking what exactly they expected - the game is called "Mech Builder", and is exactly as the name implies. The mech sets are nicely themed, and the designs are different enough to be interesting. Now the elephant in the room - the AI assets. I understand the concern many have given, and were the developer a large team or backed by a big publisher, I would heartily agree. On the other hand, from what I understand the developer is neither of these, so I am willing to be a bit more forgiving of the use of AI in the game's development. All in all, if you are looking for a relaxing little puzzle game without too much difficulty, I don't think you would do too badly with this, especially given its price (I bought it on sale for £3.87). The 3 DLC (I got those on sale, all three for around £3.50) add some extra mech sets to build - like the base game the sets are nicely themed, with some nice references.

I grew up playing and making Gundam Models so, this is relaxing to play. It has that feel of building those models without the leftover pieces and fun to paint things without making a mess.

If you love building Gunpla kits like Gundam Wing, but you don't have the money or space for them, then here's your new favorite game. There are a LOT of kits contained in the base game, plus 15 per DLC, so there is easily hours of enjoyment to be had. The pieces snap together in a very satisfying way that only the real thing can compare to. My only gripe with this game is that there are no official models/crossovers. However, the original designs feel like they're from a lost series of Gundam Wing, or concept designs from Kamen Rider, so the aesthetic is still there. Seriously, this is the best digital version of assembling kit you will find. Just remap the controls to switch tools with the shoulder buttons, map the action button to either the right trigger or A/X, and you're golden! Before you ask, yes, it's the FULL and accurate version, right down to snipping EVERY SINGLE piece out of the molds 🙂 But seriously, it's a good thing. I wish there was custom ways to paint your figures, but the full color palette and individual piece selection works just fine. Can't wait for more DLC and the upcoming 3D sequel!!
