Hi everybody :) how is everyone doing? The Persian New Year is near (April 1) also my B-Day, i can't wait to spend my free time playing Gears 3 and DA2....on April....:P

So I'm currently spending my time on learning 3D studio max and Unity3D game engine....so that i make a real video game!

I've found something in game designing the biggest limitation for making high quality games, and it's the SIZE of the game.

let me explain more, since PS3 has Blu-Ray Disk which it has 25GB per layer (i guess it has 3 layers or 2), they can use better quality textures and more polygons for their game objects,

i don't want to talk about the programing or other stuff...but for Xbox360 they only have 9GB size or at most 4 disk! which it's very rare to use 4 disk for a xbox360 game so they should be careful about using how many polygons to use for the game objects or how much quality use for the texturing..the resolution...

of course the game engine is important too specially the lighting system, how to set the shadows, reflections...if they put the quality higher they need more size....here are some examples which I've done with my 3d programs...

this is Marcus 3D model which I've downloaded from Epic game website it has 7,017 faces ready for importing to a game engine 3D Designer using a meted called normal bump map to have better quality,

they make a high res model and a low res model of the target model, then they take a normal bump map from that high res model and put it on the low res and the result will be like these pictures:

and here that model with normal bump map

the polygons are same but look how it looks like! it has much better quality! but as you can see still it's not that great also it needs better textures but for better quality they take more size...

so imagine a big map a big game like fallout3, New Vegas or GTA4 it's very hard to manage that all models all of them only on one DVD!!!!! in my opinion making games for Xbox360 is more challenging than PS3 because you have to always be careful about the size of the game! putting a game like New Vegas in one DVD is very hard indeed rather than a Blu-Ray 50GB size!

here are another example pics:

I've imported my HD car model on my Game Engine in a tutorial racing game see my car looks pretty good without any materials but look how many faces it has! 420,000!! it will add lots of size to the game indeed.

with a good texturing you can prevent the low polygons at least, there are so many plug-ins which can help a lot though.

the point of this blog was to inform you guys,gals to know don't think Xbox360 can't run a game with Killzone 3 quality but it will at least need 8,10 DVDs for that :lol: it all depends on that Game Engine too,

and also making multiplatform games are more challenging cause they need to be very accurate to fit the game at most on 3 DVD 9!

Thanks for reading :)
