while I'm not a huge fan of akabur's constant delays in any project he does (Hell Iris was modded content he added later into the official project for PT I think some people forget that.) I will say when the games are complete they are playable experiences (save for witch trainer from what I can tell, but that seems to have been a mess from the start.) but it basically goes, his numerical system, then silver which pretty much means complete but not Polished to where it could be, then Gold.
so how I see it so far
PT, a Mess but a polished mess that's playable.
WT, Barely playable mess,
PS, something so basic I'm shocked it isn't finished, I think he just ran out of ideas for transformations and jokes.
SC34, his biggest undertaking but far more playable and organized then his previous games despite being highly undeveloped and grindy still, also if you were going to mod a game this would be the one as it's would probably be the easiest to add characters, costumes, quests, without it standing out too much as the story goes since the PC has an entire cyro chamber of sluts. so this is the game that could be the most expansive as well XD.
