Inoshishi said:I was thinking the same, if a demo that lasts a couple of mins is almost 1gb in size, the full game can't be too big can it?
I do want it to be good though because from the short taste the demo gives it does look fantastic.
The engine and assets account for quite a large chunk of the overall filesize. Most demos have the whole shebang included, with the remainder of the filesize going towards maps, weapons, features etc not shown in the demo. You can have the engine be a huge behemoth to fit on discs, but the actual levels and such are usually quite small compared to it. Half Life 2 is a good example of this.
