No..Its not the issue zaxotes..
Whats the problem in getting dual layer DVD...More important thing is that you will be getting your dream Cricket game,which till now considered only to gameplay but now it is looking forward to graphics also...
In short,You are getting a complete game that any International company was unable to do till now..
EA for example saves those textures as BMP files inside the game, so there's no compression applied to them. Using PNG like TAOC proabably does means the file size increase isn't that sort of magnitude.A 887kb Stadium '.big' file grows to 11.6mb when High Quality images and realistic items are added into it.
What will be the approximate size of the alpha version?
