I am sure he is not to cocky accepting help; however... the situation is probably a bit more complicated. As well i do think he is very talented, because the project, a EVE-like space game, is a herculean feat. The issue is on "another spot"... because this game simply needs a capable engine and apparently those "free engines" are not fully capable of handling it, from what i understand.

I am not a dev, so my judgement considering such matters is limited. I can just say as much, by my rational knowledge "every engine is different, and got is pros and cons"... and not every engine is capable of everything.

Perhaps there is still some free engine capable of handling it... i dunno... i lack the knowledge.

Just be aware... apparently he is still "single"... and the game is huge. So, a engine able to "unload" (by having a lot of utilities) lot of work is probably the stuff he is looking out for... i dunno,

Well the issue is a bit comparable the the tax-office and their demands. If someone is in a certain "bracket or level" as you say... which is not exactly poor but as well not wealthy... somewhere in between... they may have to pay taxes nearly at the level of someone actually wealthy... but they just BARELY got out of the "poor-condition". There are always some unlucky spots in which you are becoming strained the most... related on the current politics. Those extremely poor usually can "evade" most of the taxes, and the very wealthy can afford it out of their coffee-pocket at some point... but those "in between"... especially just slightly at the edge in which they was able to leave the "poor condition"... this is the most tricky spot.

Sounds like a skill issue.

I can not agree but i am not sufficiently knowledgeable to disagree. The only game made in Godot that is somewhat comparable to his project is "Full Scale-Invasion", but only by the looks. If i go into the details... looking at the assets used and the mechanics involved... Astrox as a project is another league. I just think, if Godot is not able to provide lot of utility in order to handle the huge amount of assets and scripts, it surely is very difficult to "move it over". There is a reason why so many of the most successful games are not made using Godot. I would not say "those devs using Unity, they all lack the skill". Godot is good for a simple design, and yes... i know games very well and i can judge its complexity. "Full Scale-Invasion" for example is very low on assets but surely... it got the traits of a typical Indie game and the stuff those Indie-gamers love. It is in no way comparable to a game like EVE Online... which is basically the intended direction of Astrox.

Anyway, if you think you can fully move the game over to Godot while offering the same functionalities currently offered... simply LOSSLESS... then feel free to offer him your service; i would be impressed.

If i would compare it with another game of somewhat (not entirely yet, there are still lesser assets involved) comparable scale it would be Underspace ,https://www.gog.com/en/game/underspace which is basically going into the direction of "Freelancer" which is surely in some way a impressive game with a high complexity. However... Underspace is another game made by using Unity. Either they all "lack the skill" or there is another reason they prefer a "paid engine".

Indeed, SpaceBourne 2 is another impressive game, yet, no one is doubting the skill of those devs involved. Despite its high complexity... there are countless bugs and it will still take a long time for this project to become fully mature.
