It won't be purposely abandoned and he isn't milking, but in addition to other things I've mentioned previously....
Both SG and this game are way, way too big. Too much branching. Too many route combinations. Way too many LI's. I think the "sweet spot" for LI's is between 3-8. Depending on game complexity. These both have like...10-15 each?
You can handle one of the games being that way. Have a "main" game and a simpler side-game. But both of these are mains. And they're both really big main games at that. This is practically trying to do Depraved Awakening and COBD...at the same time.
Regardless of Ocean's skill level (which is very high) and his PC's (which are very good). I just can't see them be completed. And that really sucks because they're both really good games. If they weren't, I wouldn't care as much as I do. To clarify something earlier, I said "purposely" abandoned. I don't think he'll ever do that. He's put way too much into it to say "I'm done". The "abandonment" as in de facto-abandonment or something. The longer it goes, and the more complex it gets. The more he'll wear down. The less interest the game will get. The odds just aren't favorable. I guess abandonment via attrition is what I'm talking about.
I want to be an optimist. But I can't see it. I'd give it like a 10% chance. The current schedule isn't sustainable. The typical game is completed in 2-3 years. These games are on pace for a decade or more. Something will happen, sooner or later. It has to.
I think the best course is to work on SG 85% of the time. And then work on the re-work of this the rest. Do a SG update every 2-3 months, like his goal is. And do a WIAB release 1-2 times a year. And I know this isn't going to happen...but I'd re-write what hasn't been in the updates yet. Wouldn't touch the stuff already in the games. But slim down the rest of it. Simplify things. Bring the scope down and the odds of completion go up significantly.
