It'd be pretty hard to build the interior, and there's the Alliance retrofitted one in ME3, and the original SR2 in ME2.
I've been making Mass Effect guns, why not? :D
Also the amount of curves would make it difficult
It was done in minecraft quite well(even though the hull was too big for the inside), so, in theory, it should be a bit easier.
I don't think he means models.
I have been considering this but christ almighty that's a lot of curves and angles
Can someone provide a full floor plan
