I would pay for Sins of a solar empire rebellion remastered 40 bucks. Same everything except 64 multi thread no ram limit.
Same here. I would also appreciate an AI that isn't locked away in .exe or .dll files (or wherever it is), but I could certainly live without it in favour of a rebuilt 64bit game engine that this sprawling game desperately needs.
This a a game that, in its most basic vanilla form is nearly a decade old now, and yet, it still has a sizeable player base that I would consider most impressive for a ageing strategy game. Its setting can also allow it to directly tap into the similar (perhaps even larger) Homeworld player base. It also has the attraction among PC games of being pretty unique, arguably to the point of being a genre in and of itself. It has plenty of potential buyers.
I have no doubt that only rebuilding the engine for modern 64bit systems is a mammoth task on its own, but with the amount of interest still left in the game, and the lack of direct competitors, I would imagine it would be a very sound investment to make, as far as I can tell.
I'm not entirely sure the community even particularly wants developmentally time-consuming things like new ships, new game modes, or a different play-style from a possible future Sins release. Even a graphical update is largely undesired, it seems to me. The one thing people invariably mention are the technical issues such as the lack of multi-core support, 2GB RAM limit, etc.
Ironclad have outdone themselves with the long term support they have provided in the form of patches and so on, but I think it is incredibly foolish of them and their publishers to let such a game languish on an ancient engine, that is wholly unfit for realising the full potential scope of the game.
One can only hope that they took notice of the succulent gravy train that the Homeworld Remastered Collection provided for Gearbox (despite GBX releasing it in a sorry state), and make an engine remaster of their own game.
tl;dr for ironclad devs: Make a SoaSE engine remaster, and we will all throw money at you.
