for now this game start very well , shame is was abandonned
The Render are amasing !...
(For those kind of render's technically, it's of course a question of time but more a question of cost and skill)
4000 € to more than 16 000 €..for a real pro graphic-card.
Also it depend how many computers dev's have and what he use, a "simple high standar graphic" as geforce 2070, 2080 for new géneration and 280fx. Or real graphic pro-card like, firepro or quadro FX.
The enginer's that dev use to develop the game.
With this kind of material, normally you can work's on pro-progammes 3d makers, like maya or 3ds max, first one is especially great for caracters and animated them (he is use in a lot of game like call of duty, by blizzard etc ) and3 ds max (more for build environement) you can also works on 4 screen'simultaneously but you need around 6 computers....renders takes 1 to 7 day's , to depend the complexity of the scene..
This programme still "royal way's" for developed hight quality game and animeted renders.but there required a real solid formation for knowing use it and they're licence still expensive...
Since 15 years now a lot a new "free" program" are creat for help creation of some people..they become quikly popular
Most time for this kind of game, dev's use enginers like unity, vn, rempy etc..(best adobe fuse CC, blender)
there are more cheaper, more light and easiers to use in fact.
But more limited and loud for created a good visual game and for some a visual novel..
(for exemple for make move the caractere face or eyes in rempy, you've got to creat gift of the eyes one by one and them use an atl for created the loops of time to aninated a simple "winks" (clein d'oeil)....It s long too created and at the end.heavy....
