I enjoy the game and when it is complete, I plan to play it through.
And I have a huge amount of respect for the ambition of the project. Keeping the story straight, and writing the game, and coding, so it works is a MASSIVE achievment.
So, why three stars?
Because I think this will lose more followers over time, and fail to appeal to new players.
For one, it is completely, utterly, and entirely unplayable without the walkthrough. There is too much happening, that involve too many jumps, timelines, and choices as you progress, to make it through the content without a handhold. I'm not against walkthroughs or mods, at all. They help navigate choices that sometimes seem counter-intuitive, help guide to different endings, find missed content, etc.
That isn't the case here. You literally can't play the game without a walkthrough.
The second major issue is having a clue what is happening, when you load a save on a new build. I'm lost, and end up needing to start a new game. Of course, thanks to walkthrough changes as the game progresses, that can become inevitable anyhow.
The third issue is the age of the game. It is six years old now. The dev continues to update and make progress, so my concern isn't that the game will die, but at this rate, even for the literal mountain of content there is now, it could take another six years to finish. And it looks, feels, and plays quite dated. The experience is ultimately worth it, in my opinion, but I fear it will turn away prospective new players, and even long standing players may find the game has aged poorly and give up on it.
My verdict is, this game is a masterpiece of coding, just to make all of its variables work. It has an interesting story, an insane amount of content, and, especially when complete, utterly worth your time.
But the age it shows, the knowledge that competition could be far away, and the inability to play without a step-by-step guide that, if you mess up while following could lead you to go mad to figure out what you have to correct to advance, strongly detract from the game's appeal.
I like it. I think it's worth it. I can't wait for it to finally be complete and to play through it all. I think it is worth respect, and worth consideration. But I'm not blind to its flaws, I know it is a hard sell to people, and I worry many people would find the game to old looking, confusing, and guide dependent, for it to be worth their time.
Know what you're going into, play it for what it is, appreciate the scope of the devs vision, and hopefully you'll enjoy it.
